[mythtv-users] No Sound in MythTV on WinTV PVR-350 card

I've been working on setting up a MythTV installation based on the
instructions at http://wilsonet.com/mythtv/fcmyth.php.

My PC is an Old Dell Dimension.
Processor: PIII 600
RAM: 224 MB
HDA: 20GB; /boot, /, SWAP
HDB: 20GB; /video
Video Card: ATI Rage 128 (only used during setup)
NIC: 3Com 10/11; Netgear 802.11b
Capture Card: Hauppauge WinTV PVR-350
OS: Fedora Core 4; TWM (no KDE or GNOME)

As you can see, this is an older machine (though I've seen success
stories on far less) but it's mostly an experiment right now. If I can
get everything working, I'll probably upgrade hardware down the road.

I've got the machine mostly working (X/MythTV, Video, TV listings,
Remote Control) but I can't seem to get the sound working through
MythTV. What's really strange to me is that if I run:

dd if=/dev/video0 of=/dev/video16 bs=64k

Through an SSH terminal while at the main MythTV screen, I can hear my
audio (if I shut down X and run the appropriate ivtvctl commands, I
can see video to go with the audio). But If I select the "Watch TV"
option in Myth, I get an error:

Error opening audio device(), the error was: Illegal seek

And I'm given to the option to watch TV without sound. Not very useful.

Here's all the mentions of the word 'audio' in the last 350 lines of
my syslog:
[root at mythtv mythtv]# tail -n 300 /var/log/messages | grep audio
Nov 15 16:03:26 mythtv kernel: tveeprom: audio processor = MSP4448
(type = 1b)
Nov 15 16:03:28 mythtv kernel: ivtv0: Allocate DMA encoder PCM audio
stream: 455 x 4608 buffers (2048KB total)
Nov 15 16:03:35 mythtv kernel: cx8800: Unknown symbol cx88_audio_thread
Nov 15 16:03:35 mythtv kernel: cx8800: Unknown symbol cx88_set_tvaudio


I'm guessing it's related to the cx88_audio_thread stuff, but I could
be wrong (it happens a lot :).
