Internal speakers on Asahi Linux are shown are not available as output device

[lacamar]

Describe the bug
The internal speakers for M1/M2 macbooks using Asahi Linux are not shown as an output device, instead they only appear as an App output.

To Reproduce
To reproduce:

1. Start Better Control on a Macbook running Asahi Linux
2. Go to Volume tab
3. On the "Speakers" tab, the internal speakers won't be available for selection in the device menu
4. On the "App Output" tab, the internal speakers will be visible, i.e. "Macbook Pro J414 Speakers"

Expected behavior
Expected behaviour should be that the speakers are treated as an output.

Screenshots
Here are screenshots showing the issue.

*Note: there are no built-in audio headphones connected and that was the only device available in the menu at the time of the screenshot.

Additional context
The speakers on Asahi Linux use some audio plumbing to ensure the safety of the hardware and also provide DSP for audio quality. It may be that whatever is happening with this routing causes the speaker output to appear as an application output rather than direct hardware output.

I have no idea how audio works on Asahi. We'd need someone with a MacBook to fix it. I've heard it's very different from regular PipeWire and that it uses a virtual device

I'm not familiar with PipeWire development so I'm afraid I can't be of much help, but I'm willing to help test and help debug for you on my macbook m2 pro.
