Daniel: It's ok, but as far as I know, most of alsa-enabled applications don't use or are not aware of "plug" (like VLC or other).

It might be worth checking to see if the need to reset is somehow related to another bug I've filed (https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/359361) which has to do with playback issues under the same sound configuration. -- ALSA SPDIF IEC958 output no longer bit perfect (regression) https://bugs.launchpad.net/bugs/358118 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 358118] Re: ALSA SPDIF IEC958 output no longer bit perfect (regression)
Upon recommendation from the alsa developers, you should only use the plug (wrapped) device, so iec958 is correct whereas hw=0.1 is not. Regarding the symptom of only having noise after using hw=0.1, you probably need to use iecset to reset the configuration. -- ALSA SPDIF IEC958 output no longer bit perfect (regression) https://bugs.launchpad.net/bugs/358118 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 358118] Re: ALSA SPDIF IEC958 output no longer bit perfect (regression)
Ok, I did the tests you have proposed and I'm having the same issue here. mplayer works for 48khz ac3 file you've provided but only for -ao alsa:device=iec958, giving device=hw=0.1 gives noise. What is interesting - doing tests which cause a noise (with hw=0.1) , will make device=iec958 method fail too. Only alsa force-reload will bring back proper behavior. 44khz files gives noise.

Thanks for testing this in Lucid and attaching the files.

apport information
** Tags added: apport-collected
** Description changed:
My Intel HDA Audio chipset no longer provides bit-perfect output. When I
follow the ALSA bit perfect testing instructions ("Testing Your Setup"
at http://alsa.opensrc.org/index.php/DigitalOut) and play the dts-
encoded Norrlanda.wav using aplay, I get white noise instead of properly
decoded SPDIF output. In Hardy/Intrepid, I had bit-perfect output, as my
A/V receiver would switch to surround decoding mode and play sound
instead of white noise when I played DTS-encoded .wav files in Amarok.

[Bug 358118] Re: ALSA SPDIF IEC958 output no longer bit perfect (regression)
More evidence toward this being a strange ALSA driver issue. If I get a 44.1kHz DTS (or 44.1 Dolby Digital) file playing using "aplay" or "listen" music player, it outputs noise. If I then type "iecset audio 0" to give the SPDIF out the correct headers, it goes silent. If I then mute/unmute the main volume control in alsamixer (!!!) my receiver decodes the stream properly, indicating that the output is bit-perfect. So the way to get bit-perfect output is to mute/unmute the main volume control /after/ sound is playing. Hopefully someone can confirm this one... -- ALSA SPDIF IEC958 output no longer bit perfect (regression) https://bugs.launchpad.net/bugs/358118 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Also, using the test sample "ac3_the_other_side_48khz.wav" from http://www.kellyindustries.com/sounds.html, I can get bit-perfect output using the following command: mplayer ac3_the_other_side_48khz.wav -ac hwac3 -ao alsa If I play any of the 44.1kHz files, I do not get bit-perfect output, and only hear noise from my AV receiver. Interestingly, if I tell mplayer to use "-ao alsa:device=iec958" it works, but if I tell mplayer to use "-ao alsa:device=hw0.1" (the digital output), it outputs noise. I still can't get any 44.1Khz DTS or AC3 files to play bit-perfectly, though. -- ALSA SPDIF IEC958 output no longer bit perfect (regression) https://bugs.launchpad.net/bugs/358118 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
