I have a USB video capture card that I'm trying to use on my Linux box.
When a plug the card, the sound part of it is detected as a USB audio device:
cat /proc/asound/pcm | grep "USB"
02-00: USB Audio : USB Audio : capture 1
I tried to capture the audio from this device and everything is working ok.
The problem is that when I want just to listen TV (not record) I get no sound at all.
I need in some way connect the input from card 2 to the output of card 0 (my real sound card).
By now, I got this working with the following command:
sox -t ossdsp -r 8000 -w -c2 /dev/dsp2 -t ossdsp /dev/dsp
This is working for me, but after some time the audio start to lag.
So my question is: Is there a smart way to connect this two sound cards without using sox?
