New update ruining audio, roll back?

I updated to 1.1.3 media server yesterday and since then all my 5.1 and higher audio now stutters permanently. How do i roll back to 1.0.3? as I had no issues with that version. I can’t find installers anywhere.

See my post in this thread:

Thank you!

I have found the updates folder but can’t figure out how to install the previous version, can anyone help?

Ive tried swapping out the contents folder for the old one but then the app won’t open, can any help?

See my post that I already linked.
First you uninstall the current Plex server using the regular method for uninstalling programs and then you install by clicking on the installer in the update folder of the version you want to install.

I am not sure of the exact procedure if you are not using Windows but the Windows procedure is pretty straight forward.
