I've been having some weird audio issues when watching certain shows on certain channels. The Big Bang Theory on C4HD, and also Person of Interest on an unknown channel (i forget which) as specific showings. the SD versions play correctly (E4 for big bang).

I basically only get atmospheric audio, and no voice dialog when watching these 2 shows.
Big Bang i would only get audience laughter. Using the audio channel > voice description plays the audio channels correctly, but i obviously then get the voice description audio aswell.

other shows on C4HD, and other channels (BBC2 HD for example) will play audio fine.

i run a celeron nuc as the FE, with HDMI audio using alsa:pulse 5.1 in the sound settings. running a speaker test shows everything is ok with the setup. so far the only solution i've found is to drop back to stereo (with 5.1 upmixing if i desire) which isnt ideal.

any ideas as to whats wrong or what i can change to fix this in 5.1 mode?
