You may want to hack ich.c and either 1) disable the microphone-only recording channel or 2) at least make it registered _before_ the generic input channel, especially if you want to record something through the non-microphone input jack. A patch that disables the microphone channel can be found at: http://home.the-7.net/~ab/ich-nomic.diff The problem is: the ICH chipset has two distinct recording channel, one for every possible input source (line-in, CD-ROM, mic, modem and so on) and the other for the microphone only. The ICH driver utilizes this feature and registers two recording channels, the generic one first then the microphone-only one. But due to the LIFO characteristic of the recording channel selection, the mic-only channel gets chosen by the first application that opens /dev/dsp.
