Dear all, I bought Zidoo Z9S for replacement of old HDX1000 (still working well, but lucks support of new formats). I configure it and connected to my projector (HDMI) and audio system (AV-OUT). But audio is not working. I have 3,5" 4 pole connector and RCA on other side. I have 17mm connector so both variants are covered - 17 and 14mm. When I connect cable into the AV-OUT I can hear hum until connector is in place - fully inserted. After that the hum is gone, but also there is no other sounds. I try several combination of sound configuration but non works - HDMI all combination, S/PDIF all combination. I would really like to get some information how to correctly configure sound that AV-OUT will work.
