Hi @Bert_Dijkstra,
Thanks for reaching out here. I am not too familiar how HQPlayer interacts with the SonicTransporter (and this issue is very likely outside the Roon domain) but some basic questions that may help get things going:
- Is the SonicTransporter + DAC up to date on the latest firmware?
- Does only rebooting the USB DAC get it to show up properly?
- Have you tried a different USB cable to see if this has any change in behavior?
- Have you tried re-installing HQPlayer on the SonicTransporter yet?
Also, similar behavior has been reported in the following thread, maybe this is the same behavior that @dabassgoesboomboom was experiencing?
