[alsa-devel] Sound trouble with MCP61 chipset.
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,
Takashi

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 stereo at this very instant.

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.
