Funny, I had the same problem (although not every 7-10 seconds, maybe
every couple of minutes) until I upgraded to 2.6.1 with ALSA 1.0.1. 
Maybe it's because ALSA now has a btaudio driver (snd-bt87x).  I always
figured it was some bus contention issue, maybe because of the
motherboard I have (ASUS A7N266VM, nforce based).  I'm running two
Hauppauge WinTV Stereo cards now without any problems.
