Re: [mythtv-users] RE: Configuring SPDIF digital out. (SOLVED!)
Hello all, Finally broke the wall surrounding me, my Xbox and SPDIF! Since I use the .asoundrc from the DigitalSound HowTo on the Xbox, which has Digital Output but no IEC958 device, I solved the xine troubles I was having by replacing the audio.device.alsa_passthrough_device:iec958:AES0=0x6,AES1=0x82,AES2=0x0,AES3=0x2 line in .xine/config with #audio.device.alsa_passthrough_device:default since the mixed-digital .asoundrc defaults to the SPDIF. No more problems in Xine, not even when they switch between 2-channel Stereo in menus, and full 5.1 or DTS on the DVD. Now I see the light in the end of the tunnel (and NO, it's not a train!!!) I'll think I'll go see if the STB is ready for retirement yet, since I now have a reciever to go with AC3 sound on the DVB channels as well. Thanks everybody for the invaluable help and nudges in the right direction! Happy holidays Johan ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

I might suggest that all alsa utilities, alsactl, and everything else

only
thing I did is:
Enable alsa support and driver in the kernel.
Put .asoundrc in my home directory.
Set MythTV as follows:
-Enable AC3
-Device = ALSA:digital
-Mixer = digital
and that's it. I also have all the other mythplugins working by
setting
their device
to ALSA:digital. Is my setup unique, or are people doing more than
need to
to get digital audio working?
The simpler the better. I don't care how little is installed as long as
I
can get digital output, so far no go, everything looks as if it should
be
working, just no sound :(
I'd love to know how to test spdiff out as simply as possible, if I can
bypass aplay then so much the better!
Can I stream a 48KHz file straight to spdiff out?
You can use aplay -D pcmdevice and then send it out of your spdif
whilst testing. You can get a list of all PCM devices by running aplay
-L - choose one that your SPDIF is aliased to (commonly spdif) and see
if you get any sound.
The digital sound HOWTO really does explain everything you should need
to do to get SPDIF output - the one hurdle is commonly determining
which controls in the mixer need to be set to allow this. In my most
basic asoundrc file (which sounds everything by default to my SPDIF) I
have used:
pcm.!default {
type hw
card 0
device 1
}
The card/device to specify can be determined using `aplay -l` - for my
system my SPDIF was given as device 1 - yours may be different. Note
that this device expects 48kHz audio - if it's not the same format it
may play back too slow/fast or not at all. The excellent asoundrc in
the HOWTO uses the plug and dmix plugins to allow on-the-fly rate
conversion.

Thanks everyone for keeping this thread alive.
Digital sound is now working this morning but NOT as expected (please read
on), after upgrading alsa-base to the latest version from Debian, removing
arts from the system (startup was not enabled in KDE, but I discovered
that artsd was running), and doing a new depmod after removing the oss API
related modules. I didn't have time to test this yesterday as domestic
Christmas duties are crampinmg my MythTV style ;-).
As I mentioned, I did this before with the same hardware, following the
Digital Sound Howto, and it was no problem at-all. I connected the
computer to the surround amp, fiddled with a couple of sliders in
alsamixer and we were watching our first Myth movie within about 30
seconds using ALSA:diital as the output device.
Here's what I've done now:
Kernel (2.6.14):
Sound Card Suport: M
ALSA:M
Sequencer: M (SND_SEQUENCER)
sequencer dummy client: M (SND_SEQ_DUMMY)
OSS Mixer API: M (SND_MIXER_OSS)
OSS PCM: M (SND_PCM_OSS)
OSS Sequencer: *(SND_SEQUENCER_OSS) (No option for module compile)
RTC Timer support M (SND_RTCTIMER)
Use RTC as default sequencer timer * (SND_SEQ_RTCTIMER_DEFAULT)
Verbose printk NOT SET
Debug NOT SET (perhaps I should enable this amnd look at the output??)
generic devices:
Dummy soundcard M (SND_DUMMY)
Virtual MIDI soundcard M (SND_VIRMIDI)
MOTU MidiTimePiece AV multiport MIDI M (SND_MTPAV)
UART16550 serial MIDI driver M (SND_SERIAL_U16550)
Generic MPU- UART driver M (SND_MPU401)
PCI devices:
Intel /SIS/nVidia/AMD/ALI AC97 Controller M (SND_INTEL8X0) ONLY
USB devices : NONE
OSS: NOT CONFIGURED
This is the same config as before (2.6.13 rc6 git4), with the following
exceptions for new code:
SND_AC97_CODEC did not exist, now M
SND_AC97_BUS did not exist, now M
SND_HWDEP was M, no longer exists
SND_SEQ_RTCTIMER_DEFAULT did not exist, now *
SND_ICE1724 was M by mistake, no longer configured
SND_USB_AUDIO was M, no longer set
SND_USB_USX2Y was M, no longer set
loaded sound modules are as follows:
$ lsmod |grep snd
snd_intel8x0 29596 1
snd_ac97_codec 93472 1 snd_intel8x0
snd_ac97_bus1856 1 snd_ac97_codec

soundcore 7264 1 snd
snd_page_alloc 8648 2 snd_intel8x0,snd_pcm
(I took out the oss mixer and oss pcm stuff for a clean alsa system and
did a depmod in case this was screwing me up)
I have modified /etc/modultils/alsa-base and changed:
options snd-intel8x0m index=-2
to
options snd-intel8x0m index=0
(don't know what this does, but others have done it, so thought I should
do the same)
Otherwise I'm using the stock alsa-base file

Although using a different soundcard (ATI IXP150) I checked my mixer

What does the output from /proc/asound/devices mean? It looks as if both
Card 0 device 2 and card 0 device 0 are set as digital output devices??
I get similar, and only have a single SPDIF-out (no input):
[EMAIL PROTECTED] mythtv]$ cat /proc/asound/devices
0: [0- 0]: ctl
17: [0- 1]: digital audio playback
16: [0- 0]: digital audio playback
24: [0- 0]: digital audio capture
33: : timer
(I understand that the first number represents the minor number of the
device - check the snddevices script that comes with the ALSA source).
I'd still check the IEC958 mixer settings (play some audio in a loop
whilst you are checking settings) - at least this is the way I
determined what settings were required for my card.

Re: [mythtv-users] RE: Configuring SPDIF digital out.
Does setting the mixer to digital allow volume control from mythtv of the digital out? I'd like to be able to do that. Also I'd like to be able have both analog and digital have the same output, is that possible? Don't think so - by which I mean I haven't been able to get it work! ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

Re: [mythtv-users] RE: Configuring SPDIF digital out.
I finally got it working.
Here is what I did to enable spdif output to my amp when I switched from a
SB Live! 5.1 analog surround card to the on-board audio on my Asus
motherboard.
The obvious first step was to remove the SB Live! Card from the PC. During
the Power On Self Test (POST), I entered the BIOS settings and enabled the
on-board audio. Saved the settings ant continued with the boot up.
KDE informed me that the default audio device was missing. I went to the
Start menu -- System Settings -- Soundcard Detection. KDE found my
Soundcard and played a test tune. The analog sound was coming out of my TV
Speakers and nothing was coming out of my Receiver.
I opened up a terminal and typed alsamixer. I was given an error message
:
alsamixer: function snd_ctl_open failed for default: no such file or
directory.
Googling for that error led me to believe that my modprob.conf file was to
blame so. . .

The intel8x0 is my on-board audio device, and the emu10k1 was my old card.
I
commented out the lines referencing my old sound card and made a few
number
changes in the file. This is my file after editing it.

I rebooted and still no dice. Same error message from alsamixer. I tried
creating a .asoundrc file like like the example on the ALSA website.
$ vi /home/mythtv/.asoundrc

}
ctl.intel8x0 {

Still no digital sound. I attempt to run alsamixer and receive this error
message:

It is time to update drivers and such. But first a little house cleaning.

# yum install alsa-utils

# yum install alsa-driver
I tried alsamixer again and it worked.
In alsamixer I un-muted IEC958, turned ICE958 Playback all the way down,
set
ICE958 Playback source to [AC-Link], un-muted External Amplifier, turned
PCM and Master up to 90%. ESC to exit.
--- I dont know if all of this was necessary, but it worked for me. ---
I started up mythfrontend, and navigated to Utilities/Setup - Setup -
General. On the 3rd page I selected Enable AC3 to SPDIF passthrough and
Audio output device was already on /dev/dsp.
Finish going through the menus in order to make the settings take effect.
After I verified that it worked, I spent a few minutes patting myself on
the
back, and then decided to save my settings.

I'm baffld about this.
Yes I have the libasound2 libraries installed, but these are essential,
not only to alsa, but also to about 100 other packages. There is no
alternative on my Debian system. Here are the alsa relataed packages I

Re: [mythtv-users] RE: Configuring SPDIF digital out.
From previous post:
Could someone with working spdiff post the output from
alsactl store -f somefile ?
as it looks like not all the controls are visible in the mixers.
I'm still not having any luck with this.
Would really love it if someone with a working nVidia CK804 digital out
could post the output from alsactl . as it's the only way to see what the
mixer settings really are.

You can use aplay -D pcmdevice and then send it out of your spdif
whilst testing. You can get a list of all PCM devices by running aplay
-L - choose one that your SPDIF is aliased to (commonly spdif) and see
if you get any sound.
The digital sound HOWTO really does explain everything you should need
to do to get SPDIF output - the one hurdle is commonly determining
which controls in the mixer need to be set to allow this. In my most
basic asoundrc file (which sounds everything by default to my SPDIF) I
have used:
pcm.!default {
type hw
card 0
device 1
}
The card/device to specify can be determined using `aplay -l` - for my
system my SPDIF was given as device 1 - yours may be different. Note
that this device expects 48kHz audio - if it's not the same format it
may play back too slow/fast or not at all. The excellent asoundrc in
the HOWTO uses the plug and dmix plugins to allow on-the-fly rate
conversion.

Re: [mythtv-users] RE: Configuring SPDIF digital out.
I finally got it working.
Here is what I did to enable spdif output to my amp when I switched from a
SB Live! 5.1 analog surround card to the on-board audio on my Asus
motherboard.
The obvious first step was to remove the SB Live! Card from the PC. During
the Power On Self Test (POST), I entered the BIOS settings and enabled the
on-board audio. Saved the settings ant continued with the boot up.
KDE informed me that the default audio device was missing. I went to the
Start menu -- System Settings -- Soundcard Detection. KDE found my
Soundcard and played a test tune. The analog sound was coming out of my TV
Speakers and nothing was coming out of my Receiver.
I opened up a terminal and typed alsamixer. I was given an error message
:
alsamixer: function snd_ctl_open failed for default: no such file or
directory.
Googling for that error led me to believe that my modprob.conf file was to
blame so. . .

The intel8x0 is my on-board audio device, and the emu10k1 was my old card.

commented out the lines referencing my old sound card and made a few
number
changes in the file. This is my file after editing it.

It is time to update drivers and such. But first a little house cleaning.

In alsamixer I un-muted IEC958, turned ICE958 Playback all the way down,
set
ICE958 Playback source to [AC-Link], un-muted External Amplifier, turned

Finish going through the menus in order to make the settings take effect.
