I just tested a few options. Bluetooth as a transmitter and receiver with two Bluetooth dongles (BlueWave Get and an advanced Sound Accesport Air cheapie) - works flawlessly. Also connects to my LG sound bar just fine. As a BT DAC for my iPhone 6s Plus: no problems streaming tidal or Apple Music. I have no problems connecting to the DX220 on a MacBook Pro (admittedly an older model with USB A sockets) in DAC mode but I am getting crackling sounds playing Tidal or Spotify. So right now not usable for me as a DAC due to the crackling but I’m not sure if that’s some issue on my end. It connects just fine.
If anyone has comments on the crackling issue, I’m all ears. But the Bluetooth functionality for me appears to work as advertised - what are you running into?
Main Bluetooth issue: I can't get anything other than SBC with my MBP directly (i.e. not with a BT dongle), even when forcing AptX. Not convinced my iPad is using AAC, for that matter. So when limited to SBC, sure, Bluetooth seems to work great. Efforts to force a codec switch on the DX220 using developer mode also are not working.
Other Blueeoth issues: won't connect to my LG Smart TV (which has bluetooth output), nor my Apple TV (the two don't even recognize the other exists).
As for USB DAC, doesnt work with USB-C MBPs with USB-C to USB-C cables. With an adapter and the stock cable, its crackling for everything. When I connect it to an iPad using an adapter and the stock cable, I also get crackling. These USB DAC issues were not present on the DX200.
I understand that these issues may be limited to specific devices, but they are by no means esoteric devices. I don't feel like I'm being unreasonable to point them out.
