ADDITIONAL INFORMATION
Comment 1 Nicolas Fella 2026-01-09 22:12:22 UTC
Thanks for the report.

If the sound test is working as expected that means there's no issue in KDE software. The game's audio not working suggests a problem with the game, not the Plasma desktop. 

I'd recommend you contact the game's support channels
