Random error, VBVMR_GetParameterFloat returned -6

[Glaived]

I have this error in a completely random way, I also put you the related autohotkey code to try to reproduce it

#if WinExist("ahk_exe VALORANT-Win64-Shipping.exe")
	~*u::
	~*v::
		if (vmr.strip[1].B1 == false && WinActive("ahk_exe VALORANT-Win64-Shipping.exe"))
			vmr.strip[1].B1 := !vmr.strip[1].B1
	return

	~*u Up::
	~*v Up::
		if (vmr.strip[1].B1 == true && WinActive("ahk_exe VALORANT-Win64-Shipping.exe"))
			vmr.strip[1].B1 := !vmr.strip[1].B1
	return
#if

I updated VMR to the latest version, I don't think it will fix the problem since GetParameterFloat() has not been modified since.

I confirm that the error occurs even with the latest version.

That's really weird, I can't find anything about return value -6 in Voicemeeter's docs or their header file and I could not reproduce it.

I have asked the devs about it in their discord server, once they reply I look into it.

I did a little investigating on my side. The error comes from the fact that I have an infinite loop with a delay of 500ms~ before doing a new cycle. In the cycle, there is a check of the state of vmr.strip[5].Mute == true, it is this call that causes the error.

I thought it could be due to the frequency of Voicemeeter's polling, so I did a little test (see code), but I don't get any error when trying to force the thing, I conclude that it's not due to the frequency of Voicemeeter's API call.

#include <VMR>

global vmr := new VMR().login()

loop {
    test := vmr.strip[5].Mute
    sleep 1
}

Can you give me the whole script so I can try to reproduce the error?

I'm using a home-made engine, so it will be complicated to show the code as it is. But here is the execution path.

I still can't seem to get the error :/

I don't have a very powerful PC (potato pc), would that have a link ?…

🤷

I can't reproduce the problem either. Except when it pops up randomly
