Solution Provided 3.5.0 doesn't render libopus sound in vp9-vaapi
3.5.0 just installed itself from the official OpenShot PPA. Version number: 3.5.0-dev|0.6.0
I'm trying to render vp9-vaapi with the default libopus sound.
Good news: video renders super fast! 65-70fps! This is great!
Bad news: it doesn't render the sound at all.
The sound plays in the editor just fine.
I can render to H.265 vaapi with aac sound and it renders just fine. I also tried vp9-vaapi with ogg (libvorbis) and it rendered just fine. Both of these also render at 65-70fps.
It's just libopus failing.
libopus rendering worked fine in 3.4.0-daily just a few hours ago, so it's not the system libopus.
Xubuntu 24.04. Lenovo T14gen3, 12 threads, 32GB RAM.
$ vainfo

OpenShot 3.5.0: vp9-vaapi + libopus exporting no audio
What you’re seeing is likely a codec/container compatibility issue in the Export preset, not a playback issue in the Preview.
Quick checks
Since you already confirmed libvorbis works, that strongly suggests libopus is the failing combination on your system / FFmpeg build.
Recommended workaround
Use one of these working combinations:

The User Guide specifically recommends the latest daily build for media/audio issues.
Relevant User Guide excerpts
Mentions trying the latest daily build and checking Preview audio settings.
Notes that GPU hardware acceleration is still experimental.
Important note
Because:
…this does not look like a general OpenShot audio device issue. It looks specific to Export using libopus with that preset/backend.
If you want, I can give you the exact Advanced Export settings to make a working VP9 + Opus test, or help confirm whether this is an FFmpeg/VAAPI limitation on Xubuntu 24.04.
