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.
