So I have mythTV all setup and running properly on fedora core 6. Here is my 
problem:

I can play DVD movies (ripped and non-ripped) and I get sound fine. The 
problem comes in when I try to watch live TV or record Live TV.
I can get the sound to play with a

arecord -D hw:1,0 -r 32000 -c 2 -f S16_LE | aplay -

But that doesn't allow for the 2 second buffer that mythtv has.  I figure 
the problem is with the input device  from the configure capture card in the 
mythtvsetup -> config capture cards -> audio input device.  I tired setting 
that to /dev/dsp1, but when I do that the video comes out choppy and the 
audio is very high pitched. I think the reason is because /dev/dsp1 is 
suppposed to be a oss driver, and the only driver that comes with FC6 is the 
"ALSA" driver not the oss driver. I have tried the sox method of coverting 
the stream to the oss /dev/dsp but I still get no audio from the TV.

I am currently trying to install the DEPRICATED OSS kernel module. Is this 
the correct way to go?


Thanks
