Hi RussianNeuroMancer,
I have taken Daniel's patch and wrapped it into a DKMS package. Can you please do the following:
1) Uninstall ALSA driver overrides, if any
2) Download and install http://people.canonical.com/~diwic/temp/alsa-hda-diwic-acer-8943g-dkms_1.0.23.diwic_all.deb
3) Reboot
4) Verify that it works

Given your positive response I'll send the fix upstream. Thanks!

[RussianNeuroMancer (russianneuromancer)]

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed' to 'verification-done'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.
