Hi folks -
I am having trouble getting my PVR 350 to capture/output sound. I have
been struggling with this for a couple days now, and my constant
google/list searches have yielded no joy (nor did my post to the IVTV
devel list).
I have been following Jarod's excellent guide to get this set up on a
FC3 box.
I know that the root of my problem is that I am not getting any sound on
my captures (a cat /dev/video0 > test.mpg, the test.mpg being played on
another computer).
Based on my searches, I have come up with the following common causes,
which I believe do not apply to me:
1.) The card is muted.
Nope.
ioctl: VIDIOC_QUERYCTRL
Brightness = 127
Contrast = 63
Saturation = 63
Hue = 0
Volume = 58950
Mute = 0
2.) Wrong msp3400 module being loaded.
I removed the offending msp3400 module and replaced it with one from a
hand compiled IVTV .2 sources.

and from my dmesg:

ivtv: i2c attach [client=MSP3448W-A2,ok]
I also have the msp3400 module loading before the ivtv module (from my
modprobe.conf:
install ivtv /sbin/modprobe msp3400; /sbin/modprobe --ignore-install
ivtv; /sbin/modprobe ivtv-fb
Does anyone have any other suggestions as to problems that I may be having?
thanks,
/-Will
