Assist microphone always giving "does not exist" error for Awake WAV field

[rgnyldz]

Awake WAV field does not recognize the path for some reasons. I'm not able to point to any file in my media folder.

Even if I put a WAV file in the core files right next to awake.wav like wake.wav the path /usr/src/sounds/wake.wav gives the below error in logs.

[20:09:38] INFO: Service exited with code 1 (by signal 0)
/usr/src/sounds/wake.wav does not exist
[20:09:39] INFO: Service exited with code 1 (by signal 0)
