ryujinx literally minutes before it was shut down. on steam deck at least it seems impossible for the audio to stay in sync and occasionally you have to pause emulation and resume after the sound stops to bring it back in sync. Maybe a spot of lag or frame drop when some things happen for the first time, but mostly stable 30fps. I'll probably switch to desktop once I have space to set it up if the audio desync doesn't happen there.
Oh hey, I was having this issue. Changed the audio to OpenAL, restarted, and haven't had any problems since. Might be worth a try if you haven't already.
I still have an old yuzu installed but might gibe it a go with the latest firmware and see how ot goes. Unfortunately i didn't snag ryujinx on deck but at least grabbed the source from mirrors after the fact.
Edit
With firmware 18.1.0 and matching keys it works on steamdeck, the yuzu used is out of date by a few but its close enough to the final ea version floating around. Sound is fine on the rift areas and only issue so far is sometimes the rift can look weird in the villages but its a minor cosmetic issue. Made it through the first rift with no issues and probably explored a large chunk of the map. Not seeing any slowdowns.
Thanks got it today just in case. It doesn't follow the emudeck setup if anyone else is wonderinf as they do some symlinking and maybe some preconfigued settings but they can be configured manually .
