So on my freshly built 3.1-rc1 this applied cleanly but I'm getting

errors every time I try to open the device. on the FTU.

attempting to start jack gives this in dmesg:

[ 2091.951806] stop_endpoints() [ 2197.403224] Re-using EP 81 @ffff880003560000 [ 2197.403243] attr 4 [ 2197.403929] stop_endpoints() [ 2197.403931] -- data ffff880003560000 [ 2197.403933] -- sync (null) [ 2197.403935] Unable to change format on ep #81: already in use

and hitting play on audacity results in the attached dmesg errors.

is this expected currently?

Can you try to just open either the playback or the capture stream seperately, and not both at the same time?
