Weird issue. PA refuses to use my microphone as input source. Instead, is uses whatever is currently playing. For example, if I play an MP3 or watch a movie, the sound of the MP3 or the movie is used as input. In "PulseAudio Volume Control" (pavucontrol), in the "Input Devices" tab, "Analog Microphone / Microphone / Microphone" is selected. But it doesn't matter anyway; whatever I select there, the input monitor shows activity only when playing something. The microphone works just fine (I can hear what it records if I raise the "Capture feedback" slider in kmix or alsamixer.) Gentoo Linux AMD64 PA 0.9.21.2 Kernel 2.6.34 ALSA 1.0.23
