I had this same behavior on my RH9 install until I switched to the ALSA
drivers. See my previous post entitled "Setup instructions: suggestion
re Alsa on RH9".

My hardware: Athlon 1600+ on MSI K7T turbo, Geforce 4 Ti 4200, Hauppage
WinTV PCI, sound onboard (VIA 686b).

Try disabling your audio drivers before watching live tv - this should
help to confirm if the sound drivers are causing your grief. The Alsa
drivers can be a pain to build on RH9; read my previous post before
building to save yourself some stress...

HTH,

Steve

Is this your first report of this problem? (There are other recent messages
from other people named Matthew, so I'm just checking that you are not one
of them using a different e-mail address here.) Assuming it is ...

If your guess that the problem is with capture is right (and it would be my
guess too, based on what you have told us), the next question is ...
hardware or software?

Have you captured to disk using ANY application other than MythTV?
mencoder, for example, or avicap, or vcr/avifile, or ffmpeg? (Or, for that
matters, xawtv's own crude capture facility.)

Do you have DMA enabled on the drive you are capturing to? (I confess to a
bit of uncertainty as to how RAID might interact with the required speed
needed for capture to disk.)

Does your kernel support the IDE chipset your controller uses?

I'd look at these non-Myth issues before I tried any of the things you ask
about below.

If you post again, please describe your hardware (CPU, mobo, RAM) and
describe "locks up" in more detail (can you switch to a console? ssh in?
ping the system? does it require a power-cycle reboot to come back, or
something less?).

I use RH9 (also with ALSA) and have no problems. I used the MythTV rpms
from atrpms.

I would suggest getting ALSA from http://freshrpms.net and MythTV from
http://atrpms.physik.fu-berlin.de/dist/rh9/mythtv/

These packages worked quite well from me.

You might also consider install apt-get from the freshrpms site as
well. Once you've got that set up it sucks most of the work out of
installing the right packages for running MythTV.

If I'm just recording something, not watching TV, does myth use the
sound card? It crashes just from recording.

In general, the answer is "it depends". On the vidcap card you are using,
on your kernel, and on your Myth settings.

But usually, the asnwer is yes. The btaudio driver, the other possible
source of capture sound, is something you would probably know if you were
using. If your "regular winTv" card is the WinTV Go, then either you are
using the sound card, or you are trying to use btaudio and it is not
working (it does not work with that card ... check the list archives for
details).

Reports on use of the OSS sound drivers are mixed, though my own troubles
with it were well short of anything I might characterize as a "hard crash".
Steve's suggested use of the ALSA drivers might not be required, but it is
the safe approach.

[old stuff deleted]

First thing I'd check is if the sound drivers are working in a sane
manner.

1. Exit mythtv and use mpg321 to play an mp3 file.
2. Use mplayer on the command line to play a mpg/avi file.
3. Go back into mythtv, go into mythvideo (which usually uses mplayer)
and play a mpg/avi file.
4. Watch live tv from within mythtv.

Let's say all of that works with the OSS drivers (as in: you get sound),
then the question is whether or not you're using btaudio... fix your
/etc/modules.conf so that you're no longer using btaudio, then try
mythtv to watch live tv again.

If none of the above steps worked, switch to alsa and try again... Alsa
isn't really that hard to set up. Then again, I've done it several
dozen times over the last year... ;)

AFAIK, it uses the soundcard for capturing audio unless you are running
the bt878 patch which streams directly from the capture card over the
PCI bus. If I unplug my passthru cable (from the wintv card to my sound
card input), my recorded content doesn't have audio. Same if I have the
mixer configured incorrectly.

What sound card are you running? Is it onboard?

bt878 patch? is that used in conjunction with btaudio?
Seems like that would be the preferred way to do it. Correct?

yes integrated sound card, lspci reveals:

Sorry, I meant btaudio - couldn't remember the project name. Too many
projects, too little memory...<g>

Sounds like you have the same chipset that I have. When I was running
the OSS drivers and tried to record or watch live tv, my machine would
lock up hard - power switch held in for 5 secs would not even power
down. Building and installing the Alsa drivers fixed the problem in my
case: YMMV.

FWIW, here's my LSPCI dump:

A word of warning: the Alsa drivers compiled cleanly, but I got a ton of
missing dependency warnings when I tried to run; If you experience this
behavior, you need to run "touch include/linux/workqueue.h" within the
alsa-driver-xxx directory AFTER running ./configure but before executing
build.

BTW, I have not yet tried btaudio, as Alsa is working fine for me.

HTH,

Thanks Steve

Yeah, alsa did the trick. I wonder if there are any compelling reasons
to use btaudio.

Which would have lower overhead, using btaudio or using the regular
sound card in full duplex?

A normal dual tuner setups would need dual soundcards too, that's 4 PCI
slots used! And especially small PC cases have only room for 2 expansion
cards or so. Hence, even a single tuner setup would most of the time need a
second (next to the on-board sound) soundcard, since on-board sound record
capabilities are dramatic most of the time.

A card with btaudio support can do without all this extra stuff.
