[mythtv-users] Onboard sound full-duplex ?

Hi there list,
I have an issue with my onboard sound card which is on my VIA KT400 board.
Upon first attempts I got the impression it could not handle full-duplex, so
I quickly added a PCI soundcard to circumvent that. Now however, I plan to
add another (a second) BT878 card and I'm rapidly running out of PCI slots.
I have to put two BT8x8 cards in, two promise 100TX2 are already in place for
the extra harddisks, so I will not have room for two soundcards, only one...
So can anyone either confirm or deny that this card is not suited for full-
duplex mode, or maybe give tips / hints on how to get fullduplex working on
it ? (a definitive Yes/No on the full-duplex mode -availability would
already help a lot).
The card is reported by lspci as this:
00:11.5 Multimedia audio controller: VIA Technologies, Inc. VT8233/A/8235 AC97
Audio Controller (rev 60)
Subsystem: AOPEN Inc.: Unknown device 01b0
Flags: medium devsel, IRQ 10
I/O ports at e800 [size=256]
Capabilities: [c0] Power Management version 2
Maybe there is another solution I just thought of: If you can make sure that
mythtv _always_ uses Card_1 for playback, there should be no problems,
right ? Can that be done or is that infeasible ? I think that would be
impossible, seen as one cannot predict which card is free at which time,
Failing all that, I'd need to convert to a 4-port SATA card (which would also
entail expensive new SATA drives! :-(( ) or any other solution, like a new
mainboard with more slots or other onboard sound or something.
I'd really like to avoid that, if at all possible.
Thanks in advance,
