Hello, I also get this issue on Fedora 30 with Wine 4.17, with the same information logged, although it also says that MP3 decoding is somehow not supported by gstreamer before the quartz warnings, and a friend of mine has a similar problem on Gentoo with Wine 4.18. It wasn't an issue under Wine 4.15 at least.
What specific messages do you see?
I have all gstreamer packages available for my system installed.
Does that include 32-bit packages?
