CMedia sound issue

hi there,
i've been trying to get my CMedia CMI8738 onboard soundcard to work in duplex mode, but it just won't work. i've tried setting: sysctl hw.snd.pcm0.vchans=4 and sysctl hw.snd.maxautovchans=4 as mentioned in the handbook and using different dsp-channels, but still the same.
4.8 stable didn't help either.

here some dmesg output: 
pcm0: <CMedia CMI8738> port 0xe400-0xe4ff irq 11 at device 12.0 on pci0

i would be very glad if somebody could help me solve this problem.

best regards,
