If the uploaded audio build only came with citra.exe, I suppose you would need to use that. Personally, I compile my own builds, so when I compiled a build with the audio commits, I got citra.exe and citra-qt.exe, both supporting audio. If you want to learn how to build it yourself there is an easy to follow guide on Citra's GitHub
here. When building the audio branch, change "
git clone --recursive https://github.com/citra-emu/citra.git" to "
git clone --recursive https://github.com/MerryMage/citra.git -b dsp_hle". Also be sure to check "
CITRA_USE_BUNDLED_OPENAL" in CMake. In my experience, the OpenAL binaries don't download correctly using CMake at the moment, so download the file
here and extract it in "
(wherever you downloaded the code to)/citra/build/externals". After that you should be able to build as the guide says without error. Hopefully this is easy enough to follow for you
Side note: I have my own Citra branch which includes the audio commits as well as CRO, fragment lighting, and save fix commits, all on top of the latest commits from the master branch. If you want to compile it instead, use the command "
https://github.com/SeannyM/citra.git -b misc-prs".
