Powertop suggested that I do: echo 1 >! /sys/module/snd_ac97_codec/parameters/power_save When I do this, if I suspend my laptop, my sound card becomes non-functional after the resume. If I send a "0" to this file and then suspend and resume again, my sound card works again. I assume there is some sort of problem powering up the sound card which is triggered by this setting. kernel-2.6.23.9-85.fc8
I have since stopped setting this to Y. However, I discovered that even with it set to N, when I hibernate, my sound card still fails to power back up. But when I suspended and resumed, it came back up OK.
What kind of laptop is this? A smolt profile would be helpful, as well as attaching the output of 'dmidecode' to this bug report. To post a smolt profile, please enter smoltSendProfile in a terminal window and provide the link given in this report. Thanks!

Well, I checked and there is no BIOS update available for the machine (you're already running the latest 1.90). I unfortunately don't have a Toshiba laptop, so I'm not sure if there is an option to disable the sound in the BIOS - I did check on my HP and it doesn't seem that there is. I wonder if there's some modprobe magic that we can use here. Can you post your /etc/modprobe.conf please?
Grrrr - Wrong bugreport :(. The part about there not being any BIOS update is correct, but the whole thing about disabling sound obviously doesn't apply :) (someone else was wanting to use a different soundcard instead of the onboard sound). Instead, can you try anything applicable at http://people.freedesktop.org/~hughsient/quirk/ and see if that helps?
The sound card seems to come back up if I do "pm-hibernate --quirk-s3-bios --quirk-s3-mode --quirk-vbe-post --quirk-vbemode-restore". The first two options seem to be required to get the screen to come back up, but they were already turned on: % lshal | grep quirk power_management.quirk.s3_bios = true (bool) power_management.quirk.s3_mode = true (bool) The same options seem to work with pm-suspend. If I let audacious keep playing during a suspend, it resumes playback without interruption, but if I let it keep playing during hibernation, I have to restart the playback. In either case, I get auditory stuttering during the shutdown and 2 pop-up messages after the resume. One says that I'm connected to the wired network, and the other says that various PulseAudio sources or sinks or somesuch have just appeared. (It gets pushed off the screen, perhaps because it's too long, so I can't read it.) But at least the sound card does seem to be powering back up.
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 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.

Well, I just did a suspend with kernel-debug-2.6.27.7-53.fc9.i686, without touching /sys/module/snd_ac97_codec/parameters/power_save (which is apparently set to 0 by default). My sound card stopped working after the resume. Is fixing this just a matter of incorporating the quirks settings I found into the released default?

Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 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.
