My Audio DSP only support 48000 HZ so I assume that opening the Alsa
Device with *-r 48000-48000* should match.
As far as I understood *-R -u vME:::28* means that everything that does
not match 48000Hz will be resampled to that rate.
And as I did not get any error message from squeezelite I think that
should do it. But that is only my personal assumption - there is no
documentation that indicates that parameters. If you have any
suggestions, happy to try it out.
