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.
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.
