The XBMC team are looking for testers for the new audio path of the OSX version of XBMC. The Mac audio path is being unified with the other version of XBMC and the developers are looking for wider testing.
If you are interested in giving it a go to the XBMC forum, download the test build and let your feedback on the forum post.
A few of us have been looking at unifying the OSX audio path with the rest of our platforms. It’s now in a place where we need some wider testing.
If you have OSX with pretty much any output device, please try the following build:
Note that you should DISABLE passthrough of the HD audio formats (E-AC3, TrueHD, DTS-MA) as not doing so may result in whitenoise or similar being output when you try and play those formats. Feel free to try them once you’ve tested it with them off, but I don’t think it’ll work (it doesn’t work here at least!)
