Emulator: audio: Failed to create voice `adc\'

Answer 1

One option, following @palehorse's terse clue, is to edit your AVD's config.ini to disable audio.

1. Android Studio > Tools > AVD manager ...

2. Against your (previously setup) Virtual Device > Actions > Down arrow [Click it] > Show on Disk ...

3. This will take you to a directory like C:\Users\<username>\.android\avd\my_API_29_-_Android_10.avd

4. In that directory edit config.ini

5. Replace ...

   hw.audioInput=yes
   

   ... with ...

   hw.audioInput=no
   hw.audioOutput=no
   

   An entry for hw.audioOutput did not previously exist.

6. Restart the emulator a few times to get rid of lingering error messages.

See Android AVD set custom hardware for other ways to disable audio.

Just go to C:\users\sahil\.android\avd and delete .lock file.
