Thanks for all the eariler comments. I am still trying to track down the cause. Is anyone else still having trouble with sound turning off on startup and on channel change of their saa7134 card? Also, thanks to the other postings I now know how to capture the debug output. Thanks. For thoses still helping debug the problem, here is my debug output: kernel: klogd 1.4.1, log source = /proc/kmsg started. >>> modprobe saa7134 cards=2 ......... kernel: saa7130/34: v4l2 driver
