Initial playback volume always 100%

iPhone X
iOS 16.1
Channels 5.5.7

For every guide channel and every source, the initial playback audio volume is 100% regardless of set iPhone volume level.

To reproduce:

  1. Set iPhone volume all the way down to zero (mute).
  2. Tap Guide tab
  3. Tap a currently playing program
  4. Tap Watch button
  5. Playback volume will be loud (seems like 100%).
  6. Press iPhone volume down button just once and playback volume goes to zero (mute).
  7. Tap Done to stop playback
  8. Repeat to play another program
  9. Volume level again is loud and not muted.

Same. Just started noticing this behavior tonight. Diagnostics submitted.

I'm experiencing this as well (iPhone 14 Pro, iOS 16.1.1, Channels 5.5.8). Diagnostics submitted.

Is there any difference between the audio drivers under settings > playback > advanced

Issue is fixed with Experimental audio driver.

How do you enable the experimental audio driver? I am seeing the same issue.
