I have Fiio BTA30 Pro device. It shows in pulseaudio output settings as my other Denon DAC 310. Denon works great.
But!!! I can’t get sound out at all from this Fiio device. Fiio has own standalone bluetooth system. It’s not confugurable from system. It can be config from own application. So no sound from Bluetooth or analog out. I tested all output settings from pulseaudio, but no sound at all from any application.
Maybe something settings is wrong. Can you solve this via remote connection to my system? It’s easiest way to solve this issue.
Something quickly, but seems, that it is some kind of compatility issue. Now when I tried again via dac-mode, audio played about 500ms and then disappeared. It is possible, that it works with dac mode, but Bluetooth mode may be more difficult.
