Ah, I haven't found it for a long time.  
I tried to change the caps in uaudio_pcm.c, 
and a sampling rate can be converted correctly as you wrote.

I'll challenge to use this converter in uaudio, too.
If I or someone will succeed in it, 
I'll write to PR usb/78028 that it should be closed except applied.
