Ok, this probably weird, but please try enabling vchans early enough
before login/X. You have either hw.snd.maxautovchans or
hw.snd.pcm0.vchans to play with.

Virtual channels is disabled by default on RELENG_6 due to issues with
other drivers, which I intend to fix and enable it as default sooner.
