yes, that's what I would expect, too.
Do you have any idea how a 350 could be so horrendously
misconfigured in order for it to:
- deliver audio when recording or watching a show after a
fresh installation of ivtv and mythTV
- no longer delivering it after at most 3 reboots?
I've checked msp3400.o (I'm loading a good one), alsamixer,
test_ioctl (mute/unmute option), msp3400 input/output options.
I've had this behaviour for a long time. I'm currently using
mythTV 0.14 (ATrpms), FC1, ivtv 0.1.19 and am recording off
the Tuner input.
Thanks
Andreas
