I have a pro-ject digital turntable which outputs audio via toslink at 96/24
I’m trying to use volumio premium (testing during my free trial) to bridge audio between my turntable and a separate amp in a different room, with toslink input.
I’m trying to use a Hifiberry Digi+ i/o optical input to capture the output of the turntable, then use multi-room setup to cast this to my second raspberry pi which has a PiFi Digi+ card with toslink output.
When I select the digital input (which displays as HiFiberry ADC), it displays “inputs 48 kHz 16 bit”. If I set this up for multi-room playback, occasionally some distorted audio is transmitted. This is because the card is not capable of detecting the incoming bitrate. Recording from this card works correctly from the command line using “arecord -D plughw:0,0 -r 96000 -f S24_3LE -d 5 -c 2 output.wav”
I think I need to hack asound.conf to force ALSA to use a sampled bitrate of 96kHz - unless this is configurable elsewhere. But I’m feeling around in the dark here. Any suggestions would be gratefully received
