When the microphone is disabled, the azalia driver gets confused on certain machines. We need to fix it (ie make the device appear play-only), but I don't have a machine that reproduces the problem. If you have some time, could you build a kernel with the AZALIA_DEBUG option, reboot using the new kernel and send me the output of dmesg once with the mic disabled in the bios and once with the mic enabled. This way we could compare them and possibly find a fix. thanks
