I already posted it ;). However, I set sysctl hw.snd.verbose=2, here it's
again [1].
It's a cheap professional audio device, IOW it's not a consumer or
semi-professional device, so cheap doesn't mean low quality. Professional
and semi-professional devices usually don't support surround sound, but at
least the professional devices provide special interfaces, such as AES/EBU
and ADAT. The card I'm using comes with two analog IOs, AES/EBU, ADAT and
it supports consumer's SPDIF.

Yes, Ruslan does or at least did follow the thread.
I set jackd to use OSS with /dev/dsp4.0, I connected synaddsubfx

Sound Buffer Size = 256 samples
Internal latency = 5.3 ms

Jack Output SampleRate= 48000
ALSA lib seq_hw.c:457:(snd_seq_hw_open) open /dev/snd/seq failed: No such

Now there sometimes is audio output and sometimes dangerous noise, that
could damage the speakers. Jack is running without real-time,
