This problem persists for me. I use an Astro headset and route audio to an Astro Mixamp Pro TR with an optical cable for my main PC audio. When Minecraft launches it causes a problem with something either the two different audio channels the Mixamp has (Astro headset, Realtek digital audio) or something that causes the gain to increase on the PC.
my work around right now is linking AirPod Pros to pc and using those the audio is completely fine.
