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 everyone - catching up on the weekend developments.

Firstly, I'm glad the GPIO suggestion has cracked the nut, so to speak. 
Precisely why Acer did things this way is a mystery, but I'm sure they
have their reasons.

wattazoum: I had a quick look at the patch.  It can actually be refined
quite a bit since most of the "acer specific" things in there are common
to other models too.  Over the next few days I'll see about doing the
refinement unless someone beats me to it first. :)  In particular, the ADC
and DAC nids don't need duplication and the capture source details can be
reused from other models too.  I've got some other pending ALC260 patches
in the works which I'm syncing with Takashi now, so I'll probably roll
these things into those in due course.

There are a few other details we need to finalise.  Firstly, there are 4
GPIO pins on the ALC260 - we need to make sure that there's no other
features on these ACER laptops which rely on them being set.  Perhaps
lobstaj or one of the others confortable with hacking can test each GPIO
pin in turn and see if it does something.  The tests thus far seem to show
that pin 1 (zero-based) switches the internal speaker / headphone output. 
In particular, I'm wondering whether one of the others has something to do
with the CD input, since er-ku has reported that he's not getting audio
from the CD drive.

We definitely do now need a list of vendor and subsystem IDs for these
Acer laptops, as AndyP has already provided.  We'll need this before any
patch can be finalised.  For those who don't know, the relevant numbers
can be found using "lspci".  Firstly run "lspci -v" to identify the sound
system and its "bus address" - the numbers which look something like

  00:1b.0

at the start of the first line of the subsystem's description.  Then run
"lspci -nv", find the entry corresponding to the "bus address" previously
identified and report the two colon (":") separated numbers in the
"subsystem" entry.  For example, on my laptop, "lspci -v" gives me the
following entry for the audio controller:

  00:1b.0 Class 0403: Intel Corp.: Unknown device 2668 (rev 04)
    Subsystem: Fujitsu Limited.: Unknown device 1326
    Flags: bus master, fast devsel, latency 0, IRQ 17
    Memory at b0000000 (64-bit, non-prefetchable) [size=16k]
    Capabilities: <available only to root>

So we note that the bus address is 00:1b.0.  Then "lspci -nv" is run.  We
find the entry for 00:1b.0:

  00:1b.0 Class 0403: 8086:2668 (rev 04)
    Subsystem: 10cf:1326
    :

and therefore conclude the numbers we need are 10cf:1326.  Note that the
bus address on different laptops could easily be different to 00:1b.0.

er-ku: I'm not surprised about the behaviour of the headphone jack with
respect to the internal speaker.  Since the internal mic was switched off
when an external one was plugged in I fully expected to find the headphone
jack behaving in a similar way.

er-ku: in connection with the beep - I must admit that I've done nothing
with the beep generator simply because I actually don't like beeps and
therefore I'm perfectly happy if this doesn't work.  Having said that,
it's interesting that you don't get beeps - my laptop beeps even if the
sound drivers aren't loaded.  That might be due to my laptop doing beeps
independently of the sound hardware though.  I'll take a look at this over
the next few days.  In the meantime, you might like to try the following
variation to the GPIO commands which get the internal speaker running. 
Replace the 3 lines added by lobstaj with:

  {0x01, AC_VERB_SET_GPIO_MASK, 0x0f},
  {0x01, AC_VERB_SET_GPIO_DIRECTION, 0x0f},
  {0x01, AC_VERB_SET_GPIO_DATA, 0x0f},

Then test the CD (and everything else) again.  Hopefully this won't stop
the internal speaker running, but there's an outside chance that it might
give you CD audio.  When testing, don't forget to unmute the CD volume
control in alsamixer and turn it up.

Rimas: as per the mailing list post: thanks for the patch.  After some
frustrating weeks it's good to be finally making progress.

As I mentioned there, it would be good to delay this patch for a day or so
while Takashi and I synchronise a series of pending ALC260 patches.  I
also want to test the NID 0x15 thing in context on my laptop before this
goes in.  If you're cool with the idea, I can push a (slightly revised)
Acer patch to Takashi as part of this consolidation patchset.
