Correction, when the SPDIF audio plays up, I do not touch my computer but simply turn the amplifier off then back on = then sound returns again Is this my amplifier hardware playing up... or does Linux somehow loose it's audio sync (for lack of a better word) with the amp???

[Bug 25632] Re: SPDIF won't play PCM after playing AC3
I tried turning off and back on my pre/pro+amp ( Yamaha DSP-A1 ) that didn't work for me nor did rebooting my computer. Since PCM via spdif should get send at a fixed clock rate, I think the computer side might go out of of sync since when it brakes. Just running speaker-test -D spdif -c 2 fixes it for me more than once. My guess is that that command restarts the clock spdif is using or reinitialises it.

[Bug 25632] Re: SPDIF won't play PCM after playing AC3
Been battling this issue every night for the last month... the suggested fix of 'iecset audio true' worked intermittedly - when it didn't I was forced to create yet another install of Ubuntu Jaunty. Discovered something VERY interesting that may save other pple some time - curious to know other pples opinion as I am relatively new to using SPDIF audio. this is what I did 1) Upgraded the latest kernel to 2.6.31-020631, as I found SPDIF less prone to requiring the iecset audio true command (I suspect the issue is with the Linux Kernel more so then ALSA). 2) Upgraded ALSA to .21 3) Once I got mythtv working happily using SPDIF audio from the local hard drive I quickly made my computer a diskless install (copied all operating system files onto a NFS mount (PXE image) onto my home server). The diskless install worked beautifully so I disconnected my local hard drive and decided to use this as a backup for when SPDIF would cease working again. 4) Low and behold SPDIF stopped working 2 days later (despite my attempts at using iecset audio true). Luckily (I thought) I had a fully tested working backup on the local hard drive... so I reconfigured the bios to boot from the local hard drive install, expecting things to work straight away. The computer started up as expected BUT a MASSIVE WTF = SPDIF audio STILL DID NOT WORK = from my prestine backup. 5) In my frustration, I turned my stereo amplifier off and the computer off for 1 hr and tried again later = Whola = SPDIF audio returned. Will continue testing.. but I'm completely confused by this. Any thoughts?? BTW: I'm running a single core Zotac Ion motherboard (NVidia ION chipset) and the latest trunk version of mythTV.

[Bug 25632] Re: SPDIF won't play PCM after playing AC3
Personally I have been waiting for a long time this bug to clear up. Until this bug clears I can not use ubuntu. This is the one usability factor that is a deal breaker for me. I just did an alternative text install setting up boxee media center on an automatic login up and to no avail alsamixer is unable to pipe audio to my sound system. IE958 1 2 (coax and optical) are shown as being off and can not be toggled within alsa mixer. By the reports here I need to install m 2 gigs more worth of software just to get audio? This is on a limited size ssd drive set up for small footprint and speed. Is this a bug in alsa or is this a bug in ubuntu? Either way is was a poor decision to include this version of whatever it is that is causing this. As a matter of fact any time I have ever used ubuntu I have had to do days worth of searching and meddling just to get audio working the way it should be. In all cases I had to remove pulse audio and use advanced mplayer configs to do it. If anyone who reads this felt valient, stop putting buggy audio drivers in your distros and develop a curses based unified interface that, unlike alsamixer, actually works. If one interface had options for passing ac3 and dts tracks through ie958 and then again playing 2 channel through ie958 as well then all of these bug reports would be nullified, no? From that point it wouldnt matter the application. I am honestly scratching my head wondering why this bug is so old. This is likely one of the larger reasons ubuntu continues to loose popularity among folks who have used linux for a while. -- SPDIF won't play PCM after playing AC3 https://bugs.launchpad.net/bugs/25632 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 25632] Re: SPDIF won't play PCM after playing AC3
I think that the fix (just like the bug itself) has nothing to do with PulseAudio. I've experienced it on my Kubuntu box, and Kubuntu doesn't even pre-install PulseAudio. As for the integration, I believe it's integrated into the Gnome DE, which is not required to run MythTV, so removing PulseAudio shouldn't be an issue.

[Bug 25632] Re: SPDIF won't play PCM after playing AC3
Peter, According to Hebert, it appears it was fixed. It seems like this bug was something of a side effect of a larger problem of how sound was handled in the first place. Considering Karmic is still really early in its development, I'd still give it a while before you go trying it out on your main/production system. Hopefully it doesn't regress back to the way it is in Jaunty now before release. Here's hoping that doesn't happen. But if it's just the Pulseaudio and Alsa packages, you could just try updating those packages and see what your results are. If this problem is on a more important machine, that might be the safer route so you can still roll back your changes. If anyone tries that out, let us know the results. -- SPDIF won't play PCM after playing AC3 https://bugs.launchpad.net/bugs/25632 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 25632] Re: SPDIF won't play PCM after playing AC3
@Peter Antoniac, @Phil. Yes, it is close. (THIS PARTICULAR BUG) At least until further notice. I'm using Karmic Koala, and like every development version, it crashes often. A couple ot these crashes, occurred while I was watching movies on VLC (SPDIF output) and the PCM sound don't close at all. I even, for the sake of testing, reset my desktop - before writing these lines - while playing sound over spdif, just to make sure. I don't recommend using it on a production machine. Wait until Karmic Koala hits Alpha 5 at least, things are about to be edgy for now own. This is a screenshot of the new advanced pulse audio control http://i43.tinypic.com/2573e52.png (don't try to set to output digital. it won't work yet) See, this is the _REAL ISSUE_ here. A proper SPDIF environment setup is also crucial to the increase deployment of GNU/Linux on the Desktop. This must be a high priority! Ubuntu as the major GNU/Linux distro should put more effort behind it. There is a Google Summer of Code Project trying to implement passthrough on FFMPEG http://wiki.multimedia.cx/index.php?title=FFmpeg_Summer_Of_Code_2009#S.2FPDIF_muxer I hope they make it.

[Bug 25632] Re: SPDIF won't play PCM after playing AC3
Hebert, Thanks for the update; that sounds like great news! Any idea if getting consistent SPDIF sound will *require* pulseaudio though? My main MythTV box is the one that uses SPDIF, and pulseaudio can occasionally result in audio sync issues with Myth. I rarely experienced it, but I removed pulseaudio anyway just because it's unnecessary for my usage. If Karmic still plays nicely with SPDIF without Pulseaudio, I'll finally be rid of this bug that's been plaguing me for 3+ years, ever since I started using MythTV! -- SPDIF won't play PCM after playing AC3 https://bugs.launchpad.net/bugs/25632 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 25632] Re: SPDIF won't play PCM after playing AC3
@phil I really can't tell you that for sure. What I _can_ tell you is that PulseAudio, is even more integrated with Karmic Koala. As you may already imagine it could translate into more problems. But, that is just a guess. I have never completely removed PulseAudio. I know all the hassle we had to endure this last year or so. But, honestly, I think PA efforts - exposing ALSA problems - is starting to pay off. I never had A/V sync issues using VLC. The only thing that happens is a slightly absence of sound (less than a second) when I return from pause. For me that's acceptable. Kamic's today has the VLC 1.0.0~rc2-1ubuntu1 version. Fedora 11 has the rc3 version. VLC 1.0 is coming out. If possible, try it out on MythTV (backend or something) XINE was always too buggy for me.

I see that you don't think it is important, which I can understand. Perhaps not too many people are using SPDIF (I have no idea of the number/percent). But I do think it is a big usability bug for the people who try to use SPDIF. It was not added just because it was longstanding; you go from perfectly functional sound to NO sound whatsoever with no sort of explanation or error given in the GUI. It's definitely a usability bug, but I agree that there are probably more important bugs out there though. My thought is that it's a usability bug, and if it's submitted and enough people agree it's important enough, it will be fixed.

[Bug 25632] Re: SPDIF won't play PCM after playing AC3
jaunty user. I recently became a big fan of boxee former xbmc user. I've always had trouble with audio in ubuntu. However jaunty seems alot better. I havn't had any analog problems at all. in boxee i just make sure that i stop any non dts aac video before starting a dts video. then when it's not using the audio device i will start my dts video.. A bit annoying but now that I unsterstand what makes it crash it makes it manageable. spdif audio always works for me. The only problem is when i run digital with dts and aac, switching back and forth between analog and digital videos. I noticed that boxee will automatically switch from digital to analog when i play an analog source. So i can leave it in digital. i just make sure i don't start analog vid clip while playing dts aac. Sometimes rebooting works, sometimes it does not. however, i have found 2 helpful tips for the less experienced linux users out there like myself, or just a means of dealing with this 1. don't start a dts or aac digital video while another program is playing something in analog or vice versa. i.e. just stop the one before you start the other. For me I use boxee. So just stoping my videos first before starting a new works fine.. no crashes. I actually mean stop the video in boxee, then start the new video in boxee. I don't know mythtv but maybe doing this could avoid an anoying crash. 2. if you do have a crash you forget or have no idea why it crashed leaving you with no dts , digital spdif do this: open up alsa mixer, turn off IEC959 disable it. then enable it again. This works for me. I have re-created the crash several time, and have done this one step and for me dts comes right back. I have been struggling with this for awhile, but these two things make it bearable. This thread came up numerous times during my many hours and hours of searching. So I hope this helps someone. I was just happy to be able to 1, know how to avoid the crash, and 2 know how to fix it. -- SPDIF won't play PCM after playing AC3 https://bugs.launchpad.net/bugs/25632 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 25632] Re: SPDIF won't play PCM after playing AC3
OP here. I blew the dust of this card recently and found I still have
the same problem... but I've found a fix which appears reasonably
robust.
1. run 'aplay -L' to get the name of the iec958 device (my EMU10K1 is
'pcm iec958:Live). You'll see something like this:
iec958:CARD=Live,DEV=0
SBLive! Value [CT4832], Multichannel Capture/PT Playback
IEC958 (S/PDIF) Digital Audio Output
2. create the file '/etc/asound.conf' and write the following to it (substitute
your iec958 device):
#
pcm.!default rate_convert
pcm_slave.sl2 {
pcm iec958:Live
rate 48000
}
pcm.rate_convert {
type rate
slave sl2
}
#---
This forces ALL output to SPDIF by default, and also resamples
everything to 48KHz. This particular card won't to 96KHz, so this is
required for a 96KHz source to play (but downsampled to 48KHz).
I guess the fix is similar to what Jean-Francois Lalande said. Results
may vary.
I think it can be done in one line without all of the resampling stuff,
but it doesn't seem to play when the input and output rates differ.
I also suspect (as above) the file which makes this bug persistent
between reboots is asound.state. It's changing something in it when the
mixer/AC3 clash, and it doesn't change itself back.

[Bug 25632] Re: SPDIF won't play PCM after playing AC3
OP here. I blew the dust of this card recently and found I still have
the same problem... but I've found a fix which appears reasonably
robust.
1. run 'aplay -L' to get the name of the iec958 device (my EMU10K1 is
'pcm iec958:Live). You'll see something like this:
iec958:CARD=Live,DEV=0
SBLive! Value [CT4832], Multichannel Capture/PT Playback
IEC958 (S/PDIF) Digital Audio Output
2. create the file '/etc/asound.conf' and write the following to it (substitute
your iec958 device):
#
pcm.!default rate_convert
pcm_slave.sl2 {
pcm iec958:Live
rate 48000
}
pcm.rate_convert {
type rate
slave sl2
}
#---
This forces ALL output to SPDIF by default, and also resamples
everything to 48KHz. This particular card won't to 96KHz, so this is
required for a 96KHz source to play (but downsampled to 48KHz).
I guess the fix is similar to what Jean-Francois Lalande said. Results
may vary.
I think it can be done in one line without all of the resampling stuff,
but it doesn't seem to play when the input and output rates differ.
I also suspect (as above) the file which makes this bug persistent
between reboots is asound.state. It's changing something in it when the
mixer/AC3 clash, and it doesn't change itself back.

I had the same problems as described by Anders Häggström kede. So, with the speaker-test command I could hear sound and it was silent for other programs. For me, the bug was solved by restarting the pulse audio server. I was planning to isolate the solution, because I tried several things. However, even after a reboot, the bug did not appear again :-D.

The problem I've had was fixed in Intrepid; as far as I can tell it had to do with a changed default behavior of ALSA (hda-intel) to set the sound format of PCM output to float instead of integer, and this is what caused the spdif output to remain silent.

Now I have found part of a solution. When I run the following commands for about 20 seconds each, I get back the PCM signal and during the speakertest, I can hear the test sound. When I stop the test sound the PCM signal is still left (as it should) but I can not play any other sterio sounds (like ogg-files for example) thru the PCM signal. If I switch to analog output, I hear the sterio sound, so the mediaplayer is obviously working. If I play AC3 or DTS, it works and when I stop the AC3/DTS signal the PCM signal swaps back, just as it should (except that it is dead silent). $ speaker-test -c2 --device cards.pcm.iec958 --rate 44100 $ speaker-test -c2 --device cards.pcm.iec958 --rate 48000 I hope this helps someone!

OK, just to sort things... maybe the above reports concern different issues.

Neither do a reboot (with deactivated alsactl restore) nor the iecset utility work...

[Bug 25632] Re: SPDIF won't play PCM after playing AC3
I can also confirm this bug in Hardy Heron. FWIW, it's also an issue in Mandriva 2008, so it's an ALSA bug not specific to Ubuntu. It seems to be a real show-stopper with the intel8x0 driver; I have another box with a newer Asus mobo (uses the hda_intel driver) also running Myth, which I was finally able to get SPDIF working with (granted, with a a different cheat in .asoundrc). Unfortunately, neither the .asoundrc above or the one from my other machine worked on this box (Abit AN8-32X) - at least when using the defaults in MythTV and Amarok. I haven't yet had the time to try these yet with all of the other options (ALSA:plug:hw0,2, etc.). This definitely occurs when switching from a PCM source to a Dolby Digital 5.1 source; if I try to play another PCM source, I can't unless I open up a terminal and issue this: iecset audio 1 and the sound returns. Even if I then do: iecset audio 0 it will still workfor a while. I often lose the sound completely, however - be it 2/3 of the way through a movie or after one or two songs - requiring the above command(s) from a terminal. This is a royal pain. I even got to the point of writing a little script to do this and ran it as a cron job every minute - but that was not acceptable either, because if it runs while sound is playing, I get a 1-2 second silent gap.

[Bug 25632] Re: SPDIF won't play PCM after playing AC3
Bug confirmed on Hardy Heron...
I found a workaround for this issue: create a file .asoundrc in your
homedirectory containing:
pcm.!default {
type plug
slave {
pcm spdif
rate 48000
format S16_LE
}
}
It initiates a route for PCM into spdif plugin (I guess). Then, both test with
speaker-test should work:
speaker-test -D spdif -c 2
speaker-test -c 2
These is no really a solution, because the bug is still there but a
workaround that works for me.

[Bug 25632] Re: SPDIF won't play PCM after playing AC3
Confirmed in Gutsy with Intel 82801G (ICH7 Family) integrated sound card
(module snd_hda_intel).
I normally use GNOME with the volume applet active. PCM sound is
available on analog and optical output. After playing an AC3 stream the
PCM sound only plays on analog output, unless I explicitly specify spdif
as output device, such as speaker-test -D spdif -c 2. This behavior
persists between reboots.
To get it to work again I have to stop all applications using sound and
then unload and reload the snd_hda_intel module by hand as long as the
computer has not rebooted.
As far as I can tell the /etc/init.d/alsa-utils script somehow interferes with
the settings... After a reboot a part of the /var/lib/alsa/asound.state file
was changed as follows:
Before DVD playback:
control.33 {
comment.access 'read write'
comment.type IEC958
comment.count 1
iface MIXER
name 'IEC958 Playback Default'
value '04000
}
After reboot:
control.33 {
comment.access 'read write'
comment.type IEC958
comment.count 1
iface MIXER
name 'IEC958 Playback Default'
value '068200020
}
Hope this helps; this bug gets annoying somehow... ;-)
