Not in sync with Elgato Wave:3

[peteruithoven]

What Happened

When muting the sound input by middle clicking on the indicator or the switch in the dropdown the Elgato Wave:3 updates it's button to red (indicating mute). When I however mute on the Wave nothing in the indicator seems to update.

Same goes when adjusting the input volume / gain. When adjusting the input volume in the indicator leds on the Wave update, while when the input volume is adjusted on the Wave the indicator doesn't update.

This is normally not that big of an issue, but it seems like sometimes the OS overrides the Wave back to the old input volume.
Or in some rare cases it does mute the OS because the Wave is muted, but the the OS doesn't unmute when I unmute on the Wave, meaning I need to also manually unmute the OS.

(Same goes for the audio settings btw)

Expected Behavior

Ideally the OS (inc the indicator) also updates when mute or input volume / gain is adjusted on the Elgato Wave:3, keeping things in sync both ways.

Steps to Reproduce

1. Adjust mute or input volume / gain on Wave

Platform Information

elementary OS 5.1.7 Hera

Looks like the pretty low level context_state_callback or context_events_cb functions are not even called. They do respond to the mute/unmute key on my keyboard for example.
context_events_cb is called when I mute/unmute the mic from the sound settings (Switchboard).
PulseAudio Volume Control also does not update.

This all seems like a bad sign, like maybe this is simply not supported by the lower tech stacks.

One more addition, the first time pressing the mute button on the Elgato the OS sound does mute, which makes things slightly more confusing. So when you start using it you have to press it's mute twice, then unmute the OS and only then you can freely use the mute button.
