Hello, I'm experiencing same issues with 5.1 sound (SBLive5.1) as in MOS1.4.5, when subwoofer and center does not make any sound. Volume sliders in livemixer affects front output only, surround, sub and center doesn't affect anything. Mixer presented on desktop is still configured for onboard sound, I didn't find how to change this, even if settings/system/audio was set to Emu10k...
That's the problem, which makes me off using MOS1.4.5 primary and I believed, that will be corrected in MOS2. But was not. It's discourage from purchase MOS2 for me. Which way can be problem solved, to correct reproduction of sound from Sub and center? Will be that resolved in perpective? IMHO fully functional sound is base feature for OS. Thanks. hippo
