I just moved away from GrapheneOS to Motorola because I decided I needed an audio jack again. There's definitely some annoying things about leaving, but at least now I can use again the three apps that didn't work for me on GrapheneOS...
I use usb-c dac and it is honestly fine. you can get one with charging bypass and keep that one with the charger
Which apps didnt work?
Which phone and is it android then? Maybe I'm out of the loop on Motorola. I just bought a pixel, thinking of trying graphene. I was a bit miffed about the lack of jack until my partner pointed out I hadn't used the one on my old phone for over a year. I'd like to in the future though.
