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.

Here's a couple of comments in reply to things raised over the weekend.

Firstly svilen: it's good to know that my hunch about the real purpose of
the VREF was correct. Why they call it a VREF (making it sound like a
reference voltage) rather than a bias voltage is beyond me. I've seen
this terminology on other audio-related documentation though, so it seems
like it's firmly ingrained in the industry.

AndyP: the newest changes including those involving the jack mode are not
in 1.0.10 so it's no surprise things didn't change for you when trying
1.0.10. The patches are in CVS though, so until a new release comes out
CVS is your best bet. Lee's comment is worth keeping in mind though: your
ACER might use different ALC260 chip pins for the various outputs, so CVS
might only partially fix your issue. Note also that currently the jack
mode controls are active only for the "fujitsu" and the "test" models.
This may change as other developers with alternative hardware have a
chance to test the mode control with the other alc260 models.

For those who can't get sound out of some or all of their laptop outputs
under the alc260, the alc260 "test" model (also new to CVS) should assist
in working out how these laptops are connected internally. As er-ku
suggests, it should at least allow one to get sound out and work out what
controls were needed to do so. Rather than making the use of this model
the permanent solution for such situations though, the information thus
gathered could then be used to tweak the driver to support these other
variations on chip pin use. The big advantage of the "test" model is that
people can do this testing without having to patch ALSA.

jwoithe, thank you so much for your help. I personally appreciate it.
I have a question that i've already raised on the mailing list, but there
either was no reply, or I missed it. And the question is simple: why is
the "test" model considered a debug level feature? Was it really
essential?

And another question: what's the easiest way to compile alsa modules with
those debug features enabled, if I already have my distro-supplied kernel
and headers, where I bet CONFIG_SND_DEBUG is not defined? Can this be done
by appending an argument to `make` or so?

Thanks.
