I couldn't get the AC97 Driver working on my Motherboard ( Realtek ALC850 Chipset) which is why i switched to the SBLive Card. Although That was with Icaros 1.26 I don't think the Audio Drivers changed in 1.30.
The one minor problem is the additional THEMES do not appear to work although the assigns for SYS:THEME and SYS:THEMES appear to be correct. Still get the error THEMES: does not exist.
