Hello everyone,

I'm experiencing an issue with the AudioManager on my Zebra device. Despite attempting to adjust the volume, it seems to be locked at a constant level and does not change. Here are the details:

• Device Model: WS5001
• Android Version: 11
• Headphones: HS3100 BT
• Issue Description: When I try to increase or decrease the volume using the the AudioManager in my app, the volume remains unchanged. It appears to be fixed at a specific level.
• Steps Taken:
  1. Checked if the volume is not fixed.
  2. Ensured the app has permissions to change the volume.
  3. Tested in AudioManager.MODE_IN_COMMUNICATION and AudioManager.MODE_IN_CALL for AudioManager.STREAM_MUSIC and AudioManager.STREAM_VOICE_CALL channels.
  4. After calling the method to modify the volume, the volume bar changes momentarily but then reverts to the previous level.

For clarification, the sound in the app is the voice of a voice assistant, and I want to modify its volume.

Despite these steps, the issue persists. Has anyone else encountered a similar problem or have any suggestions on how to resolve this?

Thank you in advance for your help!

Best regards,
Dominika
