Google's voice assistant hasn't worked for some time because my phone's microphone seems to be used by another application.
With ADB, how do I know which applications are using the microphone?
Thank you!
UPDATE:
The output of adb shell dumpsys audio is as follows

I don't know, but it seems that the microphone is not in use by any application, or maybe I am wrong?
You can try using this command :
adb shell dumpsys audio
In the output look under Audio Focus stack entries (last is top of stack).It will show the the package name of the app using microphone
Example (When I am using microphone in whatsapp) the output was:
source:android.os.BinderProxy@829ac54 -- pack: com.whatsapp -- client: [email protected]@e5a922d -- gain: GAIN_TRANSIENT -- flags: -- loss: none -- notified: true -- uid: 10165 -- attr: AudioAttributes: usage=USAGE_MEDIA content=CONTENT_TYPE_MUSIC flags=0x800 tags= bundle=null -- sdk:30
