oss_digi96 and vmixer issues in FreeBSD 9

[RussianE39]

Hi! Is there any caveats with such combination ?

tank# cat /dev/sndstat
OSS 4.2 (b 2005/201111231712)BSD (C) 4Front Technologies 1996-2011
Kernel: FreeBSD 9.0-PRERELEASE #1: Wed Nov 23 21:41:34 MSK 2011

after doing vmixctl attach dsp and trying to use /dev/dsp I've got no sound and this in dmesg:

osscore: Trigger failed
osscore: Output timed out on audio engine 2/'RME Digi96/8 PAD (vmix)' (count=0)
osscore: Output timed out on audio engine 2/'RME Digi96/8 PAD (vmix)' (count=0)

This is stat from /dev/sndstat when vmix is attached and I try to play something in oss client app:
