Created attachment 61773 [details] Skyrim SE intro logs, Wine Staging 3.12 no music
This log still shows the same problem:
91730.063:00ae:warn:xaudio2:IXAudio2Impl_CreateSourceVoice OpenAL can't use this format and no FFmpeg, so giving up
Check the configure output in config.log. If you build from the official Arch PKGBUILD, it's in src/wine-staging-64-build/config.log. It may give a hint why it can't find libavutil and/or libavcodec. It will also print "XAudio2 WMA conversion won't be supported" if it fails to find ffmpeg.
I missed the error due to a case sensitive search...
I have some good news: the patch fixes all the sound/music/voice/scripts for me.
The issue was effectively related to my build. I won't lie: building and running a custom Wine version turned out to be pretty painful. It took me a lot of time, but once I had it properly built, everything seemed to work! I had visual artifacts but there's an other issue for this. This patch makes Skyrim SE playable, thanks!
(Note: I reported the build issue to the maintainer of the Arch package, I hope that the next release will be built with ffmpeg)
