SubjectALSA:usb audio Higher sample rates on usb audio no longer working.
Upon switching from 4.19.0 to 4.20.0, pulseaudio started complaining
that sinks that previously worked are no longer supported.

On 4.19.0 trying 24 bit 88200, 176400, and 192000 I get the following
output from pulse.
resampler.c: Forcing resampler 'copy', because of fixed, identical
sample rates.sink-input.c: Created input 15 "Playback Stream" on
alsa_output.usb-DSPeaker_Anti-Mode_X4-00.iec958-stereo with sample
spec float32le 2ch 176400Hz and channel map front-left,front-right

Switching to 4.20 gives me:
alsa-sink.c: Sink does not support sample rate of 176400 Hz
and
alsa-sink.c: Sink does not support sample rate of 88200 Hz
and
alsa-sink.c: Sink does not support sample rate of 192000 Hz

Sample rates of 44100, 48000, and 96000 work fine, but 88200, 176400,
and 192000 no longer work

Switching back to 4.19 immediately fixes the issue.


I tried looking through the alsa changelogs but there were too many to
give an obvious culprit, and haven't had time to do a git bisect. If
there's an obvious choice patch to back out I'd be grateful for the
heads up.

Regards,
Con
