I just received the skylight DM13 yesterday… after a month long shipping wait. I really think FiiO needs to get onboard with the Aliexpress shipping services because I get even electronic items in 7-8 days. I’d pay a little extra for it if I had to.
I was slightly disappointed to discover it won’t work with the BT11 (or Creative BT-W6 or the Flairmesh FMA120 for that matter). Largely because I’ve seen both the JM21 and the M23 work really well with these aptX Lossless dongles. So, I assumed that universally, across the current product range, they’d work with external UAC dongles.
The dongle powers (when “Power In” is receiving power) and connects to my receivers but it would seem it’s not negotiating and connecting on the DM13 USB side.
When I connect the DM13 to a computer, I can see it has the appropriate 2-channel USB Audio out. So, it has to be some sort of firmware capability that’s either missing or deliberately blocking it. Perhaps the DM13 currently just does UAC2 but the BT11 and other dongles need UAC1.
It’s not a huge deal because, of course, I could just listen to the digital files another way or just settle for aptX HD or wires.
Is this something that could be changed in the firmware @FiiO or was there a specific decision to not allow this?
