### Description

The issue arises whenever I connect one of my certain bluetooth speakers to laptop and also I have seen that sound devices running at AAC codec can cause this problem. Previously when I had installed dms the issue was back then started, then after some days the update came, and I switched to that newer version of dms and kernel also.

**Working Version**
dms-shell = 1.5.0-1
linux-kernel = 7.1.3.arch1-3

**Current Version (Issue)**
dms-shell = 1.5.3-1
linux-kernel = 7.1.8.arch1-3

so whenever I connect to that bluetooth sound device, even if I change the volume from the hotkey available in laptop, it won't change the volume, only if I change it from the status bar above it can be changed only.

### Expected Behavior

_No response_

### Steps to Reproduce

1. connect a bluetooth sound device which supports AAC codec
2. try to change the volume from hotkey
3. (it does show, bar changing but no effect in sound volume)

### Error Messages/Logs

_No response_

### Screenshots/Recordings

_No response_

No source file or test is named. Start by tracing how laptop volume hotkeys are handled in the DMS shell and compare that path with the status-bar volume control while using an AAC Bluetooth device. Done means the hotkey changes the actual output volume, not only the displayed bar, and the regression is covered by a reproducible test or documented verification.
