i have an Acer Aspire 5672 and had the same problems with the sound, the problem is a bug in alsa-driver.
The developers have allready fixed this bug a few days ago, just check out this link for more details:
https://bugtrack.alsa-project.org/al...ew.php?id=2104My suggestion is to download the alsa-driver-1.0.12rc3 source and patch (you can find the patch-file when you follow the link above).
Then compile the driver and you will have sound - actually it worked for me
You can also wait for the final alsa-driver version 1.0.12, the patch should then be included.
greetz,
