While perusing the Raspberry Pi Hardware documentation I came across this interesting note
My only candidate is a Khadas Tone 1 board which is rated for PCM up to 384kHz @ 32bit and DSD up to DSD256. I haven't noticed any issues with it attached to Pi 4's and Pi 5's. (Candidly, however, I don't have much high-bitrate source material to test with.)
I'm curious to know if other moOde users have experienced "reliable operation" issues with their USB DAC that might be traced to using large amounts of USB bandwidth. If so, which DAC, which Pi model, and what sort of interconnection (via direct cable, via a USB hub, etc.)
Regards,
Kent
Quote:Esoteric USB sound cards
Expensive audiophile sound cards typically use large amounts of USB bandwidth. Reliable operation with 96kHz/192kHz DACs is not guaranteed. As a workaround, forcing the output stream to be CD quality (44.1kHz/48kHz 16-bit) will reduce the stream bandwidth to reliable levels.
