Nice to see, that the HDMI-In gets attention. It’s one feature, that makes the M6 unique!
Tried the test via /opt/syna/bin/_ampclient_alpha 7… and have a question: How to get back to the linux terminal window? CTRL+C leaves me alone with a black screen, so I have to do a reset.
The “HMDI-In-Through” (via test 7) was without sound. It should be with, because it’s call AV-Test (A=Audio, V=Video).
BTW: Sound in complete system is still very choppy and disturbed in this version. Hope you correct that soon.
