Bug #: 42956
Summary: not able to set 44k sample rate with module-alsa-sink
even the hardware supports it
Classification: Unclassified
Product: PulseAudio
Version: unspecified
Platform: Other
OS/Version: Linux (All)
Status: NEW
Severity: major
Priority: medium
Component: alsa

I have a usb sound card which supports three sample rates 32000, 44100, 48000.
With pulseaudio 1.1 even I force module-alsa-sink for 44100 sample rate I can
see in the log that pulseaudio thinks that the hardware does not support it.
