Using the latest RA with updated Mesen core for NES. Have tried on multiple devices Android and Windows. Core doesn’t have sound. Settings shows not muted.
I went to the build bot and grabbed the latest from there and sound is fine now. I think it must have just grabbed a bad version upon “update all cores” in RA. https://buildbot.libretro.com/nightly/windows/x86_64/latest/mesen_libretro.dll.zip
