Low sound output after Catalina upgrade on OLD MacBook Pro

Hi,

I have an old MacBook Pro (early 2015) and now after I installed latest update I barely hear my sounds at 100% volume. I understood that on the new model Apple has some issue with the audio, but WHY IS MINE AFFECTED?

Is there any way to either unlock the 50% hardware limitation or downgrade to a old version?

MacBook Pro 13", macOS 10.15

upgrade from Catalina to Big Sur 11.5 (not 11.6) needed/ sound eruptions Avid Media Composer 2021. 9 is only compatible with Big Sur 11.5.x, not 11.6. I need to upgrade from Catalina, but only to 11.5. Is that possible? Talked to Apple, but didn't get a solution for that. The reason? The Avid MC 2021 9 has caused a wildly brutal sound eruption through speakers on 4 occasions - sound preferences are set to headphones, not speakers. Tried a restart and the noise happened threefold when starting up. What can be the cause? This started three days ago after upgrading from MC2021 6 to 9.

I don't know if there was any update from Apple, but today, after several restarts 2 issues was resolved.

The sound volume was back to normal.
"Turn display off after x minutes" is working again!

I think this sorted everything.
