Hi!
I use Volumio 2.175 on rpi3 with allo boss & there isn’t the value for 384 kHz in target sample rate.
Is it a bug or feature?
Not a bug nor a feature, we simply did not add it. But we can add it.
However it does not make any sense with the BOSS to resample to those values…
It would be great! 
I’ve read some opinions if the stream is oversampled to 32/384 boss DAC won’t do it and the result can be slightly different. I wanted to test this idea.
Added here:
github.com/volumio/Volumio2/com … a1595878ca
it will be included in next release, however it makes no sense with the BOSS
Thank you!
