Hi. I wonder if there is any way to use AC3 passthrough in XMBC with Plasma 5. I have used it with Plasma 4 and it worked. Now, there is no an option to enable it on my internal sound card. Also, I am having problems even with speaker test, after clicking the speaker in system setting, no sound is played and the app just freezes. I am using default backend (gstreamer, I guess). Any idea? Thank you very much in advance.
