Hi, sorry to disturb. I have an acer Aspire 8930 and I am fighting with sound. I have an up-to-date ubuntu Intrepid distribution. I had NO sound at all. I followed instructions upgrading to latest alsa-driver-1.0.19 added "options snd-hda-intel model=acer" to /etc/modprobe.d/alsa-base and "/usr/local/bin/hda-verb /dev/snd/hwC0D0 0x15 SET_EAPD_BTLENABLE 2" to /etc/rc.local. JOY! I have sound. So far so good. Now my problem is I do not have capture (intrnal or external mic are not working); I kept searching and found this thread. I downloaded the alsa-driver-snapshot-tiwai from ftp.kernel.org, applied the last patch (it seemed not applied in the snapshot) which went in with some line discrepancies. Removed the above settings and insatalled the new driver. Result is now I have a *very* low volume audio and I'm unsure the mic is working at all. I'm obviously missing something. Can someone be so kind to point me in the right direction, please? I'm (obviously!) ready to offer all info required. I simply didn't want to make this post any longer.

Try the latest snapshot below with model=auto option. ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-snapshot.tar.gz

If this doesn't work, please run alsa-info.sh with --no-upload option and attach the generated file. The script is found at http://www.alsa-project.org/alsa-info.sh

Hi Takashi, many thanks for the really fast answer!

I was already using that snapshot (albeit with further patches). I recompiled and reinstalled a fresh copy (to be on the safe side), but the results are the same: *very* low volume even with all mixers up.

And it's louder if you pass the model option? If so, please run alsa-info.sh on both states to compare.

thanks,

Takashi
