Muddy audio since update to Windows 10 20H2

more options

Hello


I have a problem with Firefox 87 that I am completely stumped by. Since I have updated Windows to version 20H2, my audio in Firefox became all muddy, as if only bass tones come through. Speech is completely inaudible and impossible to understand. This is a problem unique to Firefox, as other applications such as Spotify or MS Edge sound fine.

Could this be a compatibility problem with my sound card? (Creative SoundBlaster ZxR) This feels unlikely as it worked before...


Any tips? Thanks

Figured it out.

Something got borked in the Soundblaster Control Panel during the update. I have turned off all the special modes and the sound is back to normal.

If other people are experiencing this, try looking in the Soundblaster Control Panel!
