Brief description of the issue:
Please do not reset the sound settings after every start. I use voicemeeter potato and i have to reset the audio settings in the advanced sound options, every start of the MSFS
Sounds more like an issue with/of Voicemeter… Do you realy need that while playing MSFS ?.. If these tool get not enought cpu power ( because other demanding apps like msfs ) then audio crackling etc. can happen and you need to reset the voicemter sound engine.
Or what exactly you mean with “reset sound settings” ?
I set msfs to an virtual sounds card of voicemeeter potatoe in the advanced sound options in the windows settings. At the beginning of starting up msfs I can regulate the volume via voicemeeter as expected. But at a few seconds after starting msfs, obviously the sound settings will be set to standard automatically. When I look into the advanced sound settings, the virtual sounds card is selected as before. When I click on standard and back to the virtual sound card, everything works fine again.
hmm… that sounds mysterious. Not sure whether its caused from Voicemeter. I can’t retest it because I no longer use these tool ( have dedicated hardware now 
).
What I assume if there would be an issue here in MSFS would mean, that similar issue would happen for users with more than one sound-card… I remember very long ago a topic where msfs choosen the default sound-card, but can’t realy remember for details…
May be let us wait whether some other users report similar issue. Or also what other users have experiance with Voicemeter and MSFS.
