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.
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,
