Sound trouble with MCP61 chipset.

Sound trouble with MCP61 chipset.

[Steven Young]

  Hi,

  I had sent a message a couple of weeks ago regarding a somewhat
reproducible error I'm having with onboard audio for systems with the
MCP61 chipset.  Specifically, the left channel doesn't work, and emits a
high-pitched tone whenever the audio device is open.  Also, adjusting
the volume disables all sound until the kernel modules for sound are all
reloaded.  

  I didn't receive any response to that message; is this the right place
to ask? I have two machines, both with the MCP61 chipset, and both with
the same problem.  I have included the lspci -v output of one of them
below.

  Thanks,
  Steve.

Still too little information to analyze.  I see only that you
apparently have an ASUS machine with HD-audio controller.
Which version of ALSA driver are you using?  Which codec is on it?  It
can be obtained from /proc/asound/card0/codec#* file.

It might help to pass various model options for testing in most
cases.  See ALSA-Configuartion.txt for details.


HTH,

  I am using the codec "Analog Devices AD1986A", with ALSA 1.0.14rc1 
(which is the default with Ubuntu), and the snd_hda_intel kernel module.

  I had a look at that ... but I didn't see anything that looked likely
to fix my problem.  Are there any parameters you can suggest as being
relevant?

  Thanks,
  Steve.

It's way too old :)  Try 1.0.15rc2, first.

If you still have problems after installing 1.0.15rc2, please run 
http://bulletproof.servebeer.com/alsa/scripts/alsa-info.sh and send me
the resulting link.  It's probably too late to make 1.0.15, but I should
be able to get you a patch that will make the next release.

  Actually, 1.0.15rc2 fixed my problem.  I should have thought of trying
the latest version before asking alsa-devel.

  Thanks to everyone for their help! I am listening to Bust A Move in

  Hi,

  I may have spoken too soon.  While I can now use both left and right
output channels, I can't get any input off the microphone port.  When I
turn up mic boost in alsamixer, I can hear what's coming in the
microphone come out my speakers, but it never shows up on /dev/audio or
/dev/dsp.

  Steve.
