After upgrading my OS to Fedora 35, VLC started taking a long time to start playing some vídeos. After further investigation, I concluded that the problem happens depending on the audio codec used in that video file.
AAC files will play just fine, but others like AC-3 will take around 10-15 seconds to start playing. According to the logs, it will only start playing after one of the processes times out.
Hi, I test using sample file rio_bravo_mono_64_spx.ac3 from Index of /A-codecs/AC3/eac3 and play it with VLC all work fine. May be you want to upgrade your system first to see if there any new packages relate to audio (exp. alsa, wireplumber, pipewire, etc.).
