I think he's trying to read audio from the capture device of his TV card 
(/dev/dsp1) and play it back on his sound card (/dev/dsp). As I said, 
mplayer doesn't do that, but sox can. I don't know how reliable that 
method will be.

I've been trying to do the exact same thing on my system. I use ALSA, so 
I was using ecasound instead of sox. It works great for a few minutes. 
Then, at a random time after starting the transfer, my machine becomes 
very unresponsive. If I don't kill ecasound immediately, the box freezes 
and I have to hit reset. I suspected there may be problems resulting 
from timing or frequency skew between the two sound devices, but I don't 
know why it kills my box.
