Sounds like your mixer settings might be messed up. Try adjusting them
by hand to see if you can get sound. I suppose you could also try
hooking up the line-out from the tuner card to something else, to make
sure that's pumping out sometihng.

Also, if you're using the in-kernel i810 driver, you might want to try
the nvaudio driver from nvidia instead, or vise versa.

I don't think I can help with your no-sound problem in mythtv, although if
other apps work ok it is possible that it is the sound level on the input
which is the problem. Also check that nothing is holding the dsp open (like a
sound server, use 'lsof /dev/dsp' - may need to install lsof first, your
distro should have it)

For your nforce audio - by default it goes into 48kHz mode when the SPDIF
option is enabled - you can pass "spdif_status=0" to the driver when you load
it and it will get set to 44kHz instead.

/dev/dsp is not being held open. I've checked with fuser, and no
program is reported to be using it. Does lsof do basically the same
thing? I'll check on that. Have never used lsof before.

The mixer settings all look okay -- both for btaudio AND the nforce
audio. I've used aumix AND kmix (aumix doesn't see the btaudio for some
reason). Any other programs to try? Are there any other settings aside
from volue controls I should look at?


The line-out on the WinTV card works properly. I've checked it by
directly connecting it to my stereo system and output is fine. NONE of
the inputs I've checked on the card work properly. Mic, Line-In, or
CD-IN. I've used both the nvaudio and the i810 audio drivers and the
same thing happens for either.

This fixed the squeeky mp3 problem. Thanks!

Maybe something in this post helps you:
http://www.gossamer-threads.com/perl/mailarc/gforum.cgi?post=55962

I also have this box, and it is indeed working great for me. Audio in from a
Hauppauge Nexus-S to cd-in. I had to solder a cable myself though, since I
didn't have one with the two types of connectors. Working great both with
nvidia and i810_audio drivers.

Note: The drivers for my nexus card does not mess with audio devices as the
bttv seems to be doing.

Thanks to all for your assistance. Got the problem fixed. The CD
connection had come loose, which was why CD audio wasn't working. I did
not realize that the top connector on the Shuttle board was NOT line in,
but center/Bass out. Since I have a winTV401 board, I have a CD-Audio
Out jack on my board, so I connected this to the CD in jack on the Mobo
temporarily and the system seems to work quite well.

I have noticed audio isn't all that clean, though. Any recommendations
on that? It sounds a little spikey. I turned SPDIF off in the driver
so that the frequency could be changed, and that helped a little. But
not alot. Any other recommendations?

Already love it, and I am only on antenna. Cable guy is coming
tomorrow, which will hopefully fix the color problems.

Crossing my fingers for a spectacular experience with MythTV!

Thanks again!

Ciao
