Description Anton Aparin 2025-03-14 22:58:55 UTC
Sorry if this report is not really good, I just wanna help improve the UX.

STEPS I TOOK:
1. Installed kdenlive through pacman
2. Added an audio file - everything working
3. Added some images - audio still works fine
4. Added some more images - audio stopped working and doesn't start working even if restart my computer.
5. I started a new project and everything was working again, until it didn't (steps 2-4 repeated exactly)
6. Started Kdenlive thought the terminal to see the logs (https://pastebin.com/Mn5zZqDJ)
7. Pasted into Deepseek to ask for help
8. Deepseek suggested running `sudo pacman -S movit protobuf rtaudio sdl sox`
9. This fixed the issue completely (just for you, the logs of it actually working: https://pastebin.com/U0j0Y4ix)

Thanks for your report. Can you check what Audio Backend is configured in Kdenlive ?
Go in Settings > Configure Kdenlive > Playback

That is your Audio Backend and Audio Driver ?
By default, the Audio Backend should be SDL, but if for some reason you changed it to RtAudio that might explain why you needed to install rtaudio. The other packages don't really make sense.

The only backend in the list was and is SDL. While it wasn't working, I tried switching the driver and both ALSA and PulseAudio did not work.

When I cheked the audio menu in KDE, Kdenlive didn't even show up. Like this: https://i.imgur.com/vlP848E.png, but without the "SDL Application", which is Kdenlive

RtAudio isn't even in the list https://i.imgur.com/Hj6M4nT.png
