unfortunately, one of the downsides of Kernel Streaming is that it needs sole control of the output device to function. To be honest, you're best off with the DirectSound 2.0 output driver for simultaneous operation with games, unless your drivers don't play nice with DirectX. I've heard claims of improved output with certain hardware/OS mixtures, but without double-blind ABX testing to back it up, I'm going to chalk it up to placebocustics. (Anyone who
has performed such testing is free to refute me, of course.
)
Just a general tip: if you're asking for technical help on something like this, it's helpful to include system specs, i.e.: CPU, RAM, OS version, relevant hardware model and driver revision (sound card, in this case), installed software versions (foobar and DirectX, here).
And if you think installing an Audigy card is going to
improve your musical output...you obviously haven't been here very long.
To beat the Audigy-haters to the punch, it sucks for music. Best bet is to get a Chaintech AV-710, and set it up for foobar kernel streaming, and use the Audigy for movies & games--if you MUST have 5.1 surround for these things. Otherwise, forget the Audigy altogether. Going dual-card won't (in this case) add much expense, as the AV-710 can be had for ~$30 US.
