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.

How about the attached additional patch?  Please build with
--with-debug=full configure option for debugging.

I tried again the cvs-version of ~ 20:00 CET. This time the module behaves
fine. This time two cards showed up, one analog and one digital. Alsamixer
changed a bit:

aplay can play a file, but no output. With your second patch applied
against this cvs-version, everything is the same, but aplay couldn't play
anything:

$ aplay test.wav
ALSA lib pcm_dmix.c:802:(snd_pcm_dmix_open) unable to open slave
aplay: main:533: audio open error: Invalid argument
