Multimedia :: audacity and sound device

I have fix it! It was a problem with the sample rate.

I used the audacity-1.2.2.tar.gz version.

But now there's another problem:

I have enabled the "play tracks while recording" (or sth like this) and there appears no sound while recording of a new track (while the other track is playing, but silence).

Known bug in Audacity:
Recording in full duplex (playing existing tracks while recording) on some systems causes mono recordings to sound distorted or low-pitched. To work around this problem, set Audacity to record in stereo, so:
File > Preferences > Audio I/O > Channels > Stereo (2)

I record with 2 channels. (sry, I forgot to mention that)
But there is no sound from the played track.

Advice to my older audacity problem:

I guess it's the OSS sound driver system.
But when I'm using the ALSA sound driver, they're appearing some I/O errors.
(topic: http://damnsmalllinux.org/cgi-bin....=14433 )

How can I "tune" the OSS sound driver?
