Problem recording from microphone
Hi,
I have trouble recording from line-in.
As soon as some program opens /dev/dsp for reading (it seems), a loud
humming noise is produced in line-out (and nothing is recorded).
This is my system information, my mainboard (it's a Shuttle XPC SK41G,
barebone) has VIA KM266 chipset with integrated audio:

If I'm not mistaken, some of these modules belong to Alsa, is that right?
If I choose Alsa in XMMS, it doesn't work.
Is there anyone else having similar problems?
And is there anymore information I could give?
