The PTT key sound Pipewire stream is considered always active, resulting in issues with auto sample rate switching

[Arulan]

In pipewire.conf you can set the allowed sample rates that your DAC may use. This allows Pipewire to set the desired sample rate based upon the sample rate of the active audio stream.

If multiple streams are active, subsequent audio streams will be re-sampled to that of the first active stream. Once streams are idle and/or removed, it allows for new active streams to switch the sample rate again.

The current behavior of the pttkey stream is that it hijacks this functionality by always being considered active. And likely the first active stream upon logging into a new desktop session.

I'm not sure if only adding the stream when it needs to play would be the desired approach, or if there is a way for it to idle while remaining open.

Ive already tried to load it on per button press instead, but it adds a delay on the click and the sound, but ill try and figure something out.

Ive made some changes, please try the 0.2.5 version and get back to me :)

[Arulan]

@Wuild That's awesome. You're working quick! :)

It looks like the latest release (0.2.5) was not built with your latest changes. It's still on 0.2.4 code.

huh weird... did a version bump for the workflows, hopefully they got the latest push now :)

[Arulan]

@Wuild Yep, that did it.

PTT key suppression is working great! And this also solved this issue as well. I appreciate it!

EDIT: There is a slight cutoff in the sample sound (e.g. for sound on). Like perhaps it's not fully finishing before being removed?
