Yesterday night I downloaded RLcraft on Technic and then downloaded it off of twitch. Now my sound is messed up and sounds just how it sounded in minecraft. I uninstalled everything but that hasn't fixed it, I also restarted my pc three times now and ran troubleshooter and it's still not fixed. I've spent a good hour or two just trying fix my sound audio and nothing has worked. I'm starting to get annoyed and I don't want my audio to sound like distant and muffled sounds anymore.

You were able to fix it?
