So, I have found CM6206 datasheet via baidu.cn. I think most things must be
similar to mine CM6206-LX chip.
It is unclear how to download pdf file, I am not very familiar with china
language.
There is description of internal registers. There is no much interesting
settings, already existed initi
I don`t know much about it. But I can think following way as both C6206 and
CM6206LX have same ID, original Windows driver can read some internal register
and get such info.
I will try to find datasheets for both chips and see it.
As I know from mailing list archives reg init in quirk was done b

By the way CM6206-LX if different to CM6206.
CM6206 has 7.1 channels output and CM6206-LX has 5.1 channels output.
Maybe these init:

* Values here are chosen based on sniffing USB t
Yes, device seems to be working, but I am worry that there can be different
problems.
Will do detailed test a bit later.
Any way, I think it is a good idea try to fix these errors/warnings.

Does the device actually work? With different sample rates?

Do the mixer controls actually work?
