[mythtv-users] Audio stuttering

[Owen B. Mehegan]

Unfortunately, adding another PCI card is not an option at the moment. I
already have two slots taken up with IDE controller cards that run my
RAID, plus the TV tuner. The remaining two slots are used by a slot fan
that is cooling my Geforce card.

My motherboard has a Via 8233 sound card on it. I found one or two posts
mentioning success with this card in Mythtv. Has anyone else had any
luck with it?
