[SOLVED]Speakers stopped working after reboot, headphones work

Either one or two reboots ago (in the evening yesterday), I know that I had sound on my speakers, but now I can only get sound from my headphones.

I didn't notice this on the previous reboot, since I had headphones in all the time.

pacman.log from the last three days or so can be found here.

If any other information is needed to solve this I'll gladly provide it.

EDIT: Confirmed that speakers work in Windows (dualboot).

Information required for starters:

aplay -l

amixer

and evidence that you've tried solving the problem yourself. (You don't really want to be a help vampire, do you? )

Re: [SOLVED]Speakers stopped working after reboot, headphones work

Fixed it already, shouldn't have been so eager to post this thread I guess...

It turns out that something (probably the latest kernel) decided that my old /etc/modprobe.d/sound.conf wasn't good enough.
The previous version (that behaved as described in the OP) looked like this:

alias snd-card-0 snd-hda-intel
options snd-hda-intel model=auto

The current working one looks like this:

alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=acer-aspire-8930g

I'm not sure if the second line is necessary, but I added it since it allegedly helped someone in another thread. I'll probably remove it and see if it still works as it should without it.

The big change that probably fixed it is the change from auto-detection ("auto") to my laptop model ("acer-aspire-8930g").

The full list of models can be found here: http://www.mjmwired.net/kernel/Document … Models.txt
