Description of problem: I have a PowerbookG4. The pulseaudio volume is unmuted and at max, but no sound is heard. This is because the PCM volume of the card itself is at 0 by default. In F10, it was trivial enough to raise the volume, but in F11, there is no GUI way to do it, and one must run: alsamixer -D hw:0 to get access to the slider to increase it. Most users will be confused by this and just assume audio doesn't work. There should be a way to set this in the standard GUI.
You shouldn't have to got the the alsamixer tool at all. ALSA now ships a default mixer initialization database, which apparently lacks an entry for your card. If there was one PCM would have been initialized properly by default. Reassigning to alsa-utils
Please, attach output from 'alsa-info.sh --no-upload'.

The alsaunmute script should initialize volumes properly. Could you test it? (Set PCM volume to zero and run 'alsaunmute' command.)
I muted master and turned master and pcm down to 0. When I ran alsaunmute, this was not changed.

Thanks. I found the bug. Here is the patch: http://git.alsa-project.org/?p=alsa-utils.git;a=commitdiff;h=d01bbbd7061e447adc1c4acd406a3f64148a2c6e It will be included in alsa-utils-1.0.20 package. I expect to release it and update the rawhide alsa-utils package in few days.
Created attachment 342295 [details] Output of alsa-info.sh for nVidia Corporation CK804 AC'97 Audio Controller Sound is working out of the box for the F11 preview live CD. However, after a network install from the current "rawhide" tree, sound is off. 'alsamixer -c 0' reveals that the PCM channel is muted. After raising the correponding slider to a reasonable level, sound is back again. It's certainly not a database issue in this case since already the F11 preview release was working as expected.
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle. Changing version to '11'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
This message is a reminder that Fedora 11 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 11. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '11'. 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 11'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 11 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 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 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.
