------------------SPEAKER & MIC FIXED WITH KERNEL 2.6.38-11 -----------------------------

The issue appears to have been fixed with the new kernel update. & mic appear to be working ok

So here is the scoop. I have a Acer 4830t & was having "no sound" issue. So I followed Markus's (#86) advise (thanks btw). I got the speaker to work but had some issue with crackling/cracking sound while using internal mic.

I recently upgraded from kernel 2.6.38-8 to 2.6.38-11. I decided to check if the alsa modules had any patches applied -- so I uninstalled alsa-hda-dkms-acer3830tg_0.1_all.deb & ran depmod & rebooted. Viola -- speaker, headphone jack work.

Further the internal mic seems to work without crackling/cracking sound

(FYI my
/etc/modprobe.d/alsa-base.conf has
#options snd-hda-intel model=acer
options snd-hda-intel model=targa-2ch-dig --> not sure if its needed)
