Description of problem: It doesn't seem to be possible to send raw PCM audio out my motherboard's optical sound port any more. This works in Fedora 7 (for doing things like playing DVDs with 5.1 sound) Version-Release number of selected component (if applicable): alsa-utils-1.0.15-1.fc8 alsa-lib-1.0.15-1.fc8 bluez-utils-alsa-3.20-4.fc8 alsa-lib-1.0.15-1.fc8 alsa-plugins-pulseaudio-1.0.14-5.fc8 alsa-lib-devel-1.0.15-1.fc8 How reproducible: totally Steps to Reproduce: 1. try to find PCM output in mixer - it ain't there 2. 3. Actual results: no raw audio stream output Expected results: raw audio output Additional info: Here's the script I was using to successfully play DVDs on Fedora 7: amixer set IEC958 unmute amixer set 'IEC958 Playback AC97-SPSA' 0 amixer set 'IEC958 Playback Source' PCM exec mplayer dvd://1 -alang en -ao alsa:device=hw=0.0 -ac hwdts,hwac3, -monitoraspect 16:9 -fs I can't find any equivalent on Fedora 8.

After doing some reading, I have a feeling this has something to do with pulseaudio. Are there instructions for dummies somewhere on how to disable pulseaudio so I can see if it works once I do that?
OK, definitely a pulseaudio issue. I used a big hammer and moved /etc/alsa/pcm/pulseaudio.conf and /etc/alsa/pulse-default.conf to a different directory, and everything is back to "normal". Now I just gotta figure out the right way to do this without such a big hammer (if pulseaudio was supposed to make my life simpler, it didn't work :-).
remove alsa-plugins-pulseaudio; # rpm -e alsa-plugins-pulseaudio --nodeps sound comes back again. I have all other things installed but removed this one only. The issue is with that package (alsa-plugins-pulseaudio)
Perhaps related to my bug #385481 ? I can't get SPDIF out to work in F8 on an Audigy. Worked fine in F7 and lower.
okay, moved to pulseaudio.
This might be related? Installed Fedora 8 some time ago on a Dell Dimension 5150. All was well. I also use the digital output to a surround sound processor. Everything has been working well. Until today. Yum update pulled a bunch of packages having to do with Pulse Audio. After a reboot the machine lost its' ability to make noise. Periodically after updates I have to go back into the switches tab in the volume control and recheck the "SB Live Analog/Digital Output Jack" as that must be checked for this to work. It's checked. No sound. I checked all 5 devices that can be selected in the Volume Control Preferences applet: SB Live 5.1 [SB0220] (Alsa mixer)<-- What normally works SigmaTel something <---Never use. There were more after that Pulse Audio thing was installed but I'm down to 2 for a reason: yum remove pulseaudio and the problem was fixed. This: pulseaudio i386 0.9.8-5.fc8 updates 334 k is a bad egg.
For now PA doesn't support SPDIF natively. You can always bypass PA if you need spdif support by using "spdif:0" (or suchlike) as ALSA device instead of the default.
This message is a reminder that Fedora 8 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 8. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '8'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 8's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 8 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
