Hello, I've been using GrapheneOS for the past 2 years and have had a rather smooth go of everything. There is one feature I'm dearly missing at the moment however, and I'm not sure if I'm being stupid about it but I can't seem to figure out how to select my specific bluetooth inputs and outputs. I can pair bluetooth devices perfectly fine and can select through which one is 'active', however when it comes to audio inputs (microphones), there's no way to natively select which one applications use.
Some versions of android I have used have a very simple input/output device selector which works perfectly. Some apps allow in-app selection of input/output devices however most don't, and that's where my issue comes from. I have a great pair of bluetooth headphones I like using, however they have a garbage microphone in them that I cannot disable or override with the phone's native microphone, meaning I need to turn off bluetooth for any calls or voice memos. I also own a few standalone mics, notably my DJI Mic Mini and it's downright impossible for me to get any apps to detect the microphone inputs properly from them, and it's very unstable with recognized inputs being randomly selected from at times. It really sucks as I've had to use my old, dying phone to record videos with and I'm not quite at the level of wanting a standalone recorder for what I do.
If I'm just stupid and have been missing obvious features for the past 8 months I'd love to get some feedback, otherwise I think this would be a really good QOL feature to add to Graphene. Thanks for everything you've done with this awesome project!
