Hi,try another USB cable
I had a somewhat similar issue when trying to play MQA
Did you get this issue sorted? I have just purchased an R5 and a SMSL DAC/amp that plays MQA via USB only but does not work when I connect via USB....Just got my R5 in the mail today and so far I’m really impressed with its features and sound quality. A few questions that I couldn’t find answers to:
* I took advantage of the $4 Tidal deal and would like to use the R5 to stream it to my stereo system. I tried connecting it to my DAC via USB, but it didn’t work. Is it not possible to send Tidal to a USB DAC or am I missing the right setting? (I set the USB configuration to “USB DAC in”.) What about MQA —can the R5 send out decoded files via USB? Or should I just connect a line out to my preamp and stay analog?
* I can’t get the Hiby App on my iPad to recognize the R5 even if I pair the devices first. It just says “unknown remote device.” What step am I missing? I tried setting the Hiby App on the R5 to both client and server and neither one did the trick.
* Any recommendations for a good, well made 4.4 to 3.5 adapter?
Did you use an OTG usb cable? I am hoping this will solve the issue for me
