Hi. until very recently I have been able send my recordings to a capture card using an HDMI splitter which stripped the HDCP. Now, although I can record the picture there is no sound, the sound level meters on the capture card are in operation, but no sound. Is this an interference from HDCP? I am totally baffled, I have tried new cables, new splitter and reset every possible audio setting, to no avail. Any idea's?
