I am using the ALSA output to a USB DAC that supports various sample rates.
When I play files with sample rates supported by the DAC, I can see the sample rate changing in /proc/asound/card3/stream0 to match that of the file, which is exactly what I would expect.
When I play a file with a sample rate that isn't supported by the DAC the audio is being resampled (so I infer, or it wouldn't sound right). This is also what I want, since the alternative would be not being able to play the file.
However, I don't see any options to configure this resampling in the Strawberry settings menus. I assume Strawberry is only resampling as needed when the sample rate isn't supported by the audio device?
