I have some ATI "HDTV Wonder" cards which I would like to use for video
capture. The problem is that on all of the systems in which I would like
to use the card, it somehow interferes with the audio, such that I lose
the audio capability, and alsamixer only shows the cx88 capture function
of the card.
I could live with that if the capture were good, but it seems garbled,
and recording a short section of the content captured gives very low
quality audio results. I've done capture with xawtv and ffmpeg, and I
can just play the captured audio over the network to another machine
with sound, no configuration changes needed.
I can put the card in other machines and it works perfectly, with the
limitation that the machines in which it works are servers, not
something I can use for casual things.
If anyone has a thought on making this work, I'll give it a look. Since
it happens on three machines, I didn't post a lot of dmesg stuff,
without the TV card the usual sound hardware shows up, with the card
dmesg shows no indication that normal audio even exists.
All machines, working and not, use the built-in audio on the
motherboard.
Do the machines on which it doesn't work have a chipset in common?
Not a bit, mix of Celeron, K7, and early pre-HT P4, various on board
audio chipsets. And all work with other video boards, it's just the HD
board which is a problem. I have three NTSC cards which work just fine.
What about the machines on which it does work?different chipset?same
chipset?
One P4 with HT, one E6600 Core Duo.
It works only on servers? maybe a service that needs to be up and
running is not or some other service is possibly interfering? Compare
running services on the servers and workstations?Just some ideas off
the top of my head.
Off hand I'd say thanks for the questions, but the answers aren't all
that revealing.
