RetroArch gives me no audio. I eventually determined that it’s not even appearing in the Volume Mixer. In RA’s audio options, “Audio Mute” is “off”, “Audio Mixer Mute” is “off”, audio levels are 0.0, “Audio Sync” is “on”. I’ve tried all the available Audio Drivers. Nothing gets RetroArch to appear in Volume Mixer, so I get no audio from it.
Unlike my previous query, this is using the very latest nightly build, and I have also tried about a solid dozen older builds, both 32-bit and 64-bit. Clearly, something needs to be installed. This is a fresh Win7 installation with all the updates from Microsoft, but that’s it. Audio from other apps (AttractMode) does work.
Answer: DirectX End-User Runtimes (June 2010). Not a standard Windows Update package.
