When hardware buttons are used to control the volume of the remote device, the call propagates to `MediaSessionCompat.setPlaybackToRemote(volumeProviderCompat)`. However, `volumeProviderCompat` was created incorrectly when the new device volume commands were present (COMMAND_SET_DEVICE_VOLUME_WITH_FLAGS and COMMAND_ADJUST_DEVICE_VOLUME_WITH_FLAGS), i.e. with volumeControlType = `VOLUME_CONTROL_FIXED`. This resulted in `VolumeProviderCompat` which doesn't call `onSetVolumeTo` or `onAdjustVolume` and hence doesn't propagate the calls to the `Player`. Instead, it only worked with the deprecated commands which ensured the volumeControlType was `VOLUME_CONTROL_ABSOLUTE`.
This bug was introduced in c71e4bf1ff (1.0 media 3 release) when `PlayerWrapper`'s call to `createVolumeProviderCompat` was mostly rewritten to handle the new commands, but the two if-statements were not amended. Note: this change fixes the bug only for Android 11 and below. For 12 and above, there is a tracking bug for the regression that was introduced: https://issuetracker.google.com/issues/201546605

Session module
This module provides media session functionality through which media information and controls can be exposed to the Android platform, as well as to other processes and applications.
Getting the module
The easiest way to get the module is to add it as a gradle dependency:
implementation 'androidx.media3:media3-session:1.X.X'
where 1.X.X is the version, which must match the version of the other media
modules being used.
Alternatively, you can clone this GitHub project and depend on the module locally. Instructions for doing this can be found in the top level README.
