I’m using a USB-C cable with a built-in DAC on my Nothing Phone 3a (Nothing OS 3.1, Android 15), and there’s an issue where audio playback stops immediately when the screen turns off — either manually or after the screen timeout. As soon as I wake the screen, the audio resumes.
What I’ve tried:
Disabled battery optimization for music apps
Made sure “Disable USB audio routing” is off
Tested across multiple apps — same result
This doesn’t happen on other Android phones. It seems like the phone is cutting power to the USB audio device when the screen goes off.
Is anyone else facing this? Any known fix or workaround? Hoping Nothing can address this in a future update. It’s a major issue for those using USB audio.
