Hi list
Audio seems to be a common problem around here, so I am sorry to post
yet another request for help on this topic.
I bought a Hauppauge 150, model 1045 and installed ivtv 0.4. If I do
this:
cat /dev/video0 > ~/test.mpg
I play test.mpg with mplayer and get useable video, but no audio. Can
someone offer suggestions to fix this?
A peculiarity about my setup: my Linux machine does not have sound
output working yet, so I play test.mpg using mplayer on Mac OS X over
a network connection. From what I've read, this should work ok, since
the audio should be encoded inside the mpg file (if I am wrong on
this, please correct me). I've verified that mplayer is working with
video and audio by playing some other mpeg files that I hadn't
recorded off the Hauppauge card.
I did my original setup using instructions from
http://ivtvdriver.org/index.php/Howto:Debian
The resulting Debian package didn't seem to install HcwMakoA.ROM, so
I copied it to the appropriate place on my own. I can see that it
loads, so maybe this isn't the problem (see details below).
I also used the instructions from
http://ivtvdriver.org/index.php/Firmware
Things I have tried unsuccessfully:
`ivtvctl -g reg=0x808,val=0x1f` as detailed in
http://www.ivtvdriver.org/pipermail/ivtv-users/2005-November/000385.html
cold reboot
changing to various video input channels (trying to change audio
channels using `ivtvctl -q 0` gives "ioctl VIDIOC_S_AUDIO failed:
Invalid argument"; do I have the syntax wrong?)
Details follow:
linux 2.6.8 (Debian package kernel-image-2.6.8-2-k7)
ivtv 0.4 (compiled from Debian ivtv source packages; see above)
Debian 3.1/sarge with a few testing and unstable packages mixed in
Epox 9NPA motherboard with NVidia nForce4 chipset
