since 5.1.24 not just one PulseAudio sink gets created but 10

[Bard0]

i am running debian, but same happens (at least) on Arch as well. For linux VM's (with Audio being ICH AC97), there are too many sinks created on the host. I am currently working around this by using Intel Audio instead.

The host has too many audio controls (sliders) and after just 2 VM's (which use up 20 of them) i can no longer control host applications volume in the mixer.

Reproduced this locally. Investigating.

Found (and hopefully) fixed the error. I'll supply a test build shortly.

First: since you could reproduce, i trust your tests.

Second: although my comp is not set up like a dev machine, i did create a test partition, and installed the test build there. So i could see myself, that there is only 1 sink now (as it should be). But the effort to manage different versions is too high to my liking. Thus i am going to wait for the released version and only then switch back to the former Audio-Chipset-Configuration.

Well, nice to see, you got this one nailed pretty fast! Good job. :-)

Thanks for confirming -- No problem, I think this is good enough to at least try it once, as I also was able to see this locally.

The fix will be included in the next upcoming maintenance version.
