Devices:
Nothing phone 3a; Jcally JM20max
Issue:
DAC works when “Improve OTG compatibility” is switched on, but stops working as soon as the app playing audio is closed and reopened. (USB audio seems to stop whenever there is no audio for a few seconds).
The DAC can be detected by the system throughout (headphone icon displays on the notification bar).
(Temporary)Solution:
Unplug and replug the DAC. Everything then functions.
Issue re-appear when audio app is closed again.
Appendix:
I have seen a huge long thread outlining compatibility issues in past models with USB DACs including dongle DACs. The Devs seems to be surprisingly quiet about this issue.
So, are there any workaround on this problem? And, are there any dongle DACs that’s been confirmed to work with the phone 3a?
