I have usb audio device Schiit Fulla 2.
When bitperfect mode activated for this device, playback produces only white noise.
It plays perfectly good with bitperfect disabled

Can you share what application you are using?
Typically bitperfect mode only works with selected applications.
Also dmesg output is appreciated!
You need the dmesg of the attach sequence. What is printed at detach?
You might find virtual_oss in ports useful to solve your problem.
i didn't know it is working only for selected programs, i have tried playing some album through bandcamp. i will try setting up audio/musicpd and report back.
how do i get dmesg of attach sequeence?
After connecting the device:
dmesg | grep -i uaudio

i am not sure if virtual_oss could be useful, though i did not try. my intention was to disable any vchans and use the sound directly by hardware, which is what i supposed bit perfect would give. I did not know, this is limited to a number of devices. So this can be closed as expected :)
