I have several copies or F36 as independent VM’s I can use for different purposes. I find the latest update has broken audio. I can load a fresh copy and reliably apply newest patches and audio on the F36 guest disappears.
Fedora 36, latest update 7-6-2022 breaks audio while running as VM on VirtualBox - Win10
Welcome to ask @jcork when you have a minute please take a look at, Welcome to Ask Fedora! Please read me first!
Assuming the update is wireplumber 4.11, you may want to have a look at No audio device is created after updating to 0.4.11 (#303) · Issues · PipeWire / wireplumber · GitLab
Today(11-15) the patch load seems to have resolved my audio issue. Thanx to all.
