Hi there,
I found an issue when using HDMI pass through with Dolby Digital Plus (E-AC3) encoding - there is a audio delay of about 300ms. Other encodings seem to be working fine, and there is no issue when the option "Dolby Digital Plus (E-AC3) capable receiver" is not selected (which effectively disables pass through for this encoding). I'm using the 7.0.3.012c build on a WeTek Hub with an E-AC3 capable AVR between the Hub and the TV.
