Allo USBridge Signature

The log shows a S/PDIF transport

20200722 000733 worker: Audio formats (S16_LE, S24_LE)

The only way DSD can be sent over a S/PDIF connection which maxes out at 24/192K is either via DoP which would be limited to DSD64 format which is sent at 176.4K or by DSD to PCM on-the fly conversion up to 192K rate.

If your DAC supports DoP over S/PDIF then in MPD Config set the option "DSD over PCM" to Yes. If it doesn't or you are not sure then it to No.

Thank you Tim for this clear reply. I didn't know this S/PDF limitation which also explains why x86 based players based on USB connection do not face this issue. I think it's worth testing the usb path towards my DAC and evaluate its merits compared to Allo Signiture S/PDIF.
