Sometimes, after I wake up from suspend (using pm-suspend), the front audio jack stops working (no sound) after I wake up my laptop. Only after a full reboot I get it to work again.

My laptop is an HP dv6-2030sd and has an Intel sound card. The module loaded is snd_hda_intel, but removing it and adding it again has no effect. I use the ALSA sound system only, so no pulseaudio.

My question is, is there a way to get it to work again without a full reboot?

What does unloading then reloading the module do? Do you have that option? – Tim Dec 6 '11 at 14:28
In what sense? When unloaded, the sound stops working at all, when reloading it again, sound starts working again, but still no front audio. – Ikke Dec 6 '11 at 14:40
Was hoping that worked, then you could write a custom load/unload script when waking from suspend. But alas it doesn't work. Something about the S1,S2,S3 may be broken in that bios, pretty typical of machines targeted for Windows. – Tim Dec 6 '11 at 15:08
Ok, so rebooting would be the only option. – Ikke Dec 6 '11 at 15:24
Before giving up, check if there is an ALSA switch or mixer for front audio... you may just be able to turn it back on. Or maybe cycle the switch once. Check amixer contents. – derobert Dec 6 '11 at 20:41
