Bug Description

Package: linux-image-2.6.20-16-generic

On resuming from Hibernate, audio does not work on Dell Inspiron 1420. I have tried setting HIBERNATE_MODE=platform and running "/etc/init.d/als-utils force-reload" on resume. None of them worked.
Doing a reboot will bring back the sound. Resuming from Suspend will also keep the audio working.

The offending application seems to be mixer_applet2 ( that shows the speaker on the panel).
 By killing the applet before hibernating, the issue is resolved.
      So, I tested by creating a file, say, in /etc/acpi/suspend.d/.
      In the file , I do, "killall mixer_applet2"

 However, the drawback is, upon resuming the user will see a message box which asks the user whether to load or not the volume control applet. If the user chooses to load, everything is perfect. But if he chooses not to load, then the speaker icon will be gone from the panel ( the user, however, can always add it back to panel manually).
      I don't know much about gnome applets. So, I don't know how to add and remove an applet to the panel programatically.

 The above will also let you unload the "snd_hda_intel" module. It seems mixer_applet2 is what was holding references to the module. And I have found unloading the module before hibernating and loading it back on resume does solve the problem as well. I tested this scenerio from the text console in recovery mode..

After some experimentation I think a better solution is this:

killall mixer_applet2
modprobe -r snd_hda_intel

modprobe snd_hda_intel

This gets the sound module shut down and restored in the right order, and works for both hibernate and suspend. The Gnome mixer applet still annoys you on resume, but I'm not sure how to fix that in a user generic way.

The Feisty fix works, but there is still that annoying mixer applet after resume.

The updated alsa in linux-backports-modules-2.6.22 fixes the major portion of this failure. For some reason, sound is muted on resume still. Not know yet if this is the fault of the driver or alsa-lib userspace.

Work around is to adjust volume, or mute/unmute after resume (this can be automated by adding a script in /etc/acpi/resume.d/ to call "amixer set Front mute; amixer set Front unmute".

Its not a mute problem, it appears that volume is not initialized on resume. The attached file restores volume after resume. Add it to /etc/acpi/resume.d.

I'll mark it as fixed for Gutsy. Should work natively for Hardy.

Its NOT fixed for Gutsy. I have a 1420N Inspiron and the problem persists. I have installed gutsy afresh.

Even after trying out Tim Gardners resume script or Ben Collins', the sound doesn't come up after resuming. One reboot is required for the sound to come up.

same problem here, my dimension has no sound, and sometimes doesnt allow me
to resume from suspend/hibernate, how comes crappy m$ products got it

For the script to work, you must have linux-backports-modules-2.6.22-14-generic installed.

The fixes described in this bug appear to have been automatically installed on my girlfriend's Dell 1420n, but she is still having trouble with no sound after resume. This is on Feisty with no funky package changes, default install. I've tried muting and muting as described. I tried the 99-restore-volume script, but amixer says it can't find a control called Master. The only relevant mixer controls are PCM, which doesn't have a mute option, and Front, which does.
