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.

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

The first line is also present with the plain cvs-version

The line number in dmesg doesn't match with my code, so your code is likely
still older than mine.  Could you update the CVS tree?

Also, please upload the codec and asound.state files instead of pasting
them.
