CoD Warzone extremely elevated chat voice in crossplay?

Hi, I'm playing this game on PC and I want to play it with buddies who are active on PS4. When I talk to them IN THE GAME, it sounds to them as if I have a voice changer active, because my voice comes across damned elevated. I don't know why, because at the same time I checked everything and did tests on the PC to find out, but my voice sounds completely normal. Neither in the settings of Battle.net nor in-game is there anything helpful that would change and the support from Activision is also not a help. Can jmd help me?

Go to the Mw settings.

There you can make various micro settings.

This also includes increasing the voice or making it quieter

As already mentioned, I tried it again but unfortunately it didn't work.
