No Sound

Hi!

I have a Sound Blaster Live 5.1 which I am trying to get to work with
MythTV, I followed the instructions in the HOW-TO but I can't get MythTV
to play sound at all but when I do "aplay /dev/dsp" I can hear the sound
from the tv.

this is what mythfrontend says when I run it:
connecting to backend server: 127.0.0.1:6543
Changing from None to WatchingLiveTV
Input #0, mpeg, from 'rbuf://127.0.0.1:6543/mnt/store//ringbuf1.nuv':
Stream #0.0: Video: mpegvideo, 480x480, 29.97 fps, 16000 kb/s
Stream #0.1: Audio: mp2, 48000 Hz, stereo, 384 kb/s
Over/underscanning. V: 0.000000, H: 0.000000, XOff: 0, YOff: 0
Using XV port 50

I tried sampling rates: 32000, 44100 and 48000. What am I doing wrong?

Thanks in advance,
Miguel

Can we infer from this that this is a PVR-250? If so, the
HOW-TO instruction for recording from line-in don't apply.
The audio is multiplexed in the hardware encoding stream.
Either your driver modules are setup correctly to capture
audio (more likely) or PCM and Master aren't set to play
the audio (less likely). Others who are using these cards
may be able to give you more specific advice.

Yes, I am using a PVR-250 but I cannot find any info on how to set this
up in the archives, can anybody give me some pointers?

Thanks,

The most likely thing is that you didn't load the msp3400 module that got
compiled with the ivtv driver -- instead, you've got the msp3400 module from
the standard kernel compile.

I can second this one, I did it. Go to the drivers directory for your IVTV
CVS pull and do an insmod instead of the modprobe they speak of in the
docs. insmod ./msp3400.o should do it for you
