DetailsDescription:
Latest Blender package (3.4.1-13) https://archlinux.org/packages/community/x86_64/blender/ has problems on playing MP3 files. Last Package that worked was AFAIK 3.4.1-10. At first I thought it is a blender bug, but as package 3.4.1-10 did not have this bug, it must be the package. Additional info: * Blender package 3.4.1-13 * Working in package 3.4.1-10 see also: https://projects.blender.org/blender/blender/issues/104845 Steps to reproduce: Open a new VSE file (File->New->Video Editing). Drop an MP3 file to the sequencer. The playhead should be before that MP3 starts. Press play (Space). The MP3 does not play. If the playhead is placed anywhere inside the MP3, the audio starts playing. Also enabling "Caching" for that strip (Strip->Source->Caching) seems to eliminate that bug. Also WAV files does not seem to be affected. I attached a blender file demonstrating the behavior. Just open it and press "Space" to playback.

Great problem description. I can actually reproduce this perfectly between the package versions and -10 does indeed work. Very strange. I'll investigate.

Seems fine now. A simple rebuild did it, I think.

Could you check?

I don't know how to check. I'm running manjaro and the package 3.4.1-13 is still showing build date of 2023-02-07 (on stable branch) and seems to be the old thing. Probably Manjaro does not update that? I'll have to wait for 3.4.1-14 then, which is still in branch unstable.

I can't provide support for Manjaro. I suggest you just get an up-to-date Arch mirror and grab the package from there.

@Svenstaro, I repro'd this before assigning. Was just about to close it but thought I better recheck. Unfortunately it still repro's for me. Not sure what's up.

Hm indeed. I'll keep looking into it.

Ok, I managed to track it down. We're now building Blender without our buildflags. I wasn't able to figure out exactly which flag introduced the problem so I'm just disabling all of them. Please test rel-21. It worked consistently for me.
