I wish to connect the HDMI to a video projector and the audio port to a sound mixing desk. Either audio or video works fine alone but when both cables connected am getting high-pitched feedback into the sound system. I have tried disabling HDMI as an audio device but it makes no difference. Have tried more than one HDMI and audio cable - same result.
