[mythtv-users] PVR-150 no audio

[Greg Woods]

I have just spent the last several hours looking through Jarod's Guide
and searching the mailing list archives, but have not found the answer.

I replaced my pcHDTV-3000 card with a PVR-150 (I don't have any HDTV yet
anyway) because I wanted hardware decoding. I am using an analog cable
hooked to the coax input of the card. First I set up the card under
Windows to make sure it worked, the cable signal was good, etc. It works
fine under Windows. Video and audio are good.

Back to Linux, I got the ivtv drivers installed. The modules all load.
All capture tests I have run produce the same result: there is video,
but no audio. Other audio apps work fine so I believe my sound card and
ALSA drivers are configured and loaded correctly. 

The capture tests I have run include cat /dev/video0 to a file, then
reading that file with mplayer; running mplayer directly
off /dev/video0, and mythfrontend. All the same: video is good, no
audio. Mythfrontend in Watch Live TV mode will change channels, but
ptune-ui.pl will not (it SAYS the channel was changed but the running
mplayer is not affected). Running "aplay /dev/dsp" while any video is
playing also produces no sound.

The only thing I found that remotely covers this (not saying there isn't
anything else, just that if there is, I haven't been able to find it) is
a line from the troubleshooting section of the MythTV install doc, a
link to stuff specific to the PVR-250/350, which I am assuming would be
similar to the 150 because they are all MPEG2 encoder cards. It says
that no audio can be caused by loading the wrong msp3400 module.
However, I am as certain as I can be that I am loading the correct
module. I have installed ivtv-0.3.7a, but I briefly tried one of the
0.3.6 versions with the same results. If I look under /lib/module/`uname
-r` , the ivtv directory is the only one that contains an msp3400.ko
file. 

# modinfo msp3400

I do note, however, that the troubleshooting chapter says that I should
see a line that says "parm: standard int", and as you can see, there is
no such line. All I did to build the driver was "make; make install". Is
there some parameter I need to tweak to make this build correctly? Have
I done something else obviously wrong?

Thanks for any help,
