There are some techniques to extract the sound exist:
1. The simplest one is
arecord -D hw:2,0 -r 32000 -c 2 -f S16_LE | aplay -
It gives stereo, but with too long delay in sound.
2. No delay, but mono only:
sox -r 32000 -w -t alsa hw:2,0 -t alsa hw:0,0
The neighbour method for stereo
sox -r 32000 -c 2 -w -t alsa hw:2,0 -t alsa hw:0,0
lacks :(
3. Experimentally I found the middle technique:
arecord -D hw:2,0 -r 32000 -c 2 -f S16_LE | sox -q -c 2 -r 32000 -w -t wav - -t alsa hw:0,0
Stereo, no lacks, delays rarely.

You might try to use the oss emulated interface, I also had several problems with lacks, delays etc which were solved by the oss emulated access.

Issues with FM radio
Frequency shift
About a year ago (I use up2date kernels) I found that my FM radio based on AVerTV Hybrid+FM PCI (A16D) began work incorrectly: all radio stations shifted to higher frequencies on about 2.5 MHz. E.g. a station which broadcasts at 105.2 MHz will be received if I set 107.9-107.95 MHz. All stations above 105.2 MHz cannot be received, all stations below 105.2 MHz are shifted as well.
Does anybody expects the same issue? Or my chip is degraded and it should be changed by something newer?
