no problem for me, the correct sound (audio = "english") is always selected by default (even if I see in addition the sound-options Audi2-MTV, Audio3-MTV, Audio4-MTV in my list of available audio channels and what are audio-channels from other MTV-channels)
and I do not really watch MTV, only switched to the channels to check for the problem described
and even if my receiver/Neutrino-OS selects the correct audio (english) by default, my receiver would remember the audio-selection (including volume configured if not also default) for each channel separately
