Device 70:5A:6F:62:A9:1B EarFun Air Pro 3
Description of Problem:
I acquired a pair of EarFun Air Pro 3 and got the LE enabled firmware from the support (they apparently disabled it due to some phone issues...). When I connect them to my computer, I only get the left channel. The Gnome Sound settings "test" also only shows a speaker on the left side. Also, the recording is very silent (and is displayed as front left channel only as well).
Unfortunately, I don't have any other LC3 compatible device or phone to see if the earbuds are to blame. Also, I did not dive at all into le audio to be able to understand parameters and different profiles. Is there any tools to see or switch different LEaudio profiles?
