Summary: No Sound on Acer with Intel ICH6 HDA and Realtek
ALC260
Description:
I can load the snd-hda-intel module and play a file via aplay or xmms or
play a cd without any error, but I cannot hear anything neither via the
build-in speakers nor via headphones. All volume controllers are at 70%
and unmuted, except for PCM, because there is no mute/unmute-button.

Hi,
jwoithe, can you post your patch_realtek.c somewhere.
I have Fujitsu-Siemens S-7020 too. I hope your changes will work for me
too.
Actually I have sound, but the mic doesn't work.

Thanks,
Svilen

svilen - Support for the Fujitsu S7020 mappings was added to ALSA in the
1.0.10rc cycle. It is in the ALSA 1.0.10 standard release. Please ensure
you are running at least this version of ALSA.

As to your mic not working, I suspect that it might be a condensor
microphone which requires some bias voltage from the laptop (or its own
battery in some cases) in order to work. Many computer headsets fall into
this category. The existing S7020 setup does not allow for this, simply
because I have no use for such microphones (I use external preamps when
necessary since they're much cleaner). Another user has also noticed that
such microphones don't work with ALSA 1.0.10 on the S7020.

I have very recently (3 days ago) submitted a patch for consideration
which adds the ability to record 4 audio channels on this laptop. A
portion of this patch implemented a new "jack mode" control which (among
other things required for the 4 channel functionality) allows the user to
turn on the mic bias for the mic/line jack if they need it. If you grab
this patch and switch the "mic/line jack mode" control to "Mic 80pc bias"
or "Mic 50pc bias" I suspect your mic will start working (although you'll
have to turn the mic/line volume control up fairly high I suspect).

I am hoping the patch will be merged soon. Otherwise grab it from
alsa-devel
or contact me via alsa-devel and I'll get it to you privately.
