Description Craig McLure 2022-09-20 16:53:41 UTC
Since Kernel 5.19.9 the GoXLR no longer works, presenting the following error in dmesg:

[25554.653323] usb 5-3: parse_audio_format_rates_v2v3(): unable to find clock source (clock -71)
[25554.653821] usb 5-3: uac_clock_source_is_valid(): cannot get clock validity for id 41
[25554.653822] usb 5-3: clock source 41 is not valid, cannot use

My guess is that this is related to ff878b408a03bef5d610b7e2302702e16a53636e (usb-audio: Split endpoint setups for hw_params and prepare), I've not been able to directly bisect yet, but it was the only change that would apply.

We ran into a similar problem in 5.11 where the sync ep wasn't initialised prior to the data endpoint resulting in no audio (Bug #215079), I'm wondering if we've hit the same thing again now that prepare and configure are split.
