So, I just bough the PO100 Pro, for my setup with Edifier S360DB. I have tidal on my Windows PC connected to PO100 with USB C, and then with an optic cable to the speakers from there.
On Tidal, when I turn off exclusive mode, everything plays, but the MQA light on PO100 never lights up. When I turn on exclusive mode, 88.2KHz FLAC and 48KHz MQA music don't produce any sound! But the MQA indicator does light up with exclusive mode on, even with MQA passthrough disabled on Tidal. I also tried with my iPhone (using OTG lightning to USB C cable) and I get/don't get sound on the same songs.
I'm not sure whether this is a problem with the PO100, or Tidal, or even maybe the optical cable. The majority of the MQA songs on Tidal are 48KHz, so I can't go on like this. I also don't want to have to turn off exclusive mode. I'd really appreciate any help!
