Since the introduction of the Pixel 9 devices shipping with the AIDL Audio HAL, the DynamicsProcessing.BandStage can no longer be disabled. DynamicsProcessing.Mbc is used on the sample for demonstration, as it extends extends DynamicsProcessing.BandStage. The same issue occurs when using DynamicsProcessing.Eq, which also extends DynamicsProcessing.BandStage.

Steps to reproduce:

Compile and open the sample
Press the FAB to play music
In the Dynamics Processing fragment, enable 'DPE enable'
Enable MBC and lower the gain until a difference in sound is observed
Disable MBC and notice no changes in sound
Notice changing the gain slider still changes the sound

The issue is present on any device with the AIDL Audio HAL enabled (vendor.audio_hal.aidl.enable=true), so build numbers are irrelevant. The issue is confirmed to be present in AD1A.240905.004, BP22.250124.009 and all build between to name a few.
