Sound no longer working on AAO ZG5

I just reinstalled Arch on my ZG5 -- before I reinstalled everything sound-related was working by using snd-intel-hda and ALSA, all I had to do was add the line

options snd-hda-intel model=acer-aspire

in /etc/modprobe.conf, unmute the channels, and ALSA took it from there. After my reinstall, I did the same things I did to get it to work last time, and no sound appears, despite the device being listed.

Here are outputs from commands that may be useful:

aplay -l

Thanks for any help smile

EDIT: Just tested with another distro and sound works out of the box with ALSA and the same output from the above commands... hm.
