Hello Takashi and everyone,
Behringer UFX1204 and UFX1604 have sync endpoints and we set up
implicit feedback sync on them. This is against the UAC spec.
We've already fixed a major source of noise by explictly setting up
the Clock Selector. Therefore in my humble opinion we should now
disable implicit feedback sync for those two devices.
What do you think?
Thank you,
Geraldo Nascimento

implicit feedback is required for other platforms as well, for example mac osx

Pardon my ignorance, but how so? Isn't ALSA for Mac OSX just alsa-lib?
Please enlighten me.

Yes, as long as it works, we should get rid of the unnecessary
implicit-fb quirks. Care to submit a patch?
thanks,
Takashi
