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
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
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
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.
Thanks in Advance
