saa7134 TV Tuner card audio problems



I don't know about in tvtime, as I haven't really used
it, but I know in MythTV there is an option called
Time Sync which you can adjust +/- to sync up the
sound with the video.  I would assume that tvtime
probably has something similar since it's a program to
work with capture/tuner cards and it's a common
problem with some capture/tuner cards.

Also, I've looked and don't seem to have a module
saa7134-oss, but I do have a module saa7134-alsa and
I'm guessing that saa7134-alsa is the one I'm going to
need to use, but I get a fatal error everytime I try
to modprobe it.  At this point I'm just baffled as to
how I had the sound working at one point and it's
driving me crazy trying to figure out what I did that
one time.
