Hi guys, I am trying to connect my amp with my Tv using HDMI and there is no sound. I have a Pioneer VSX 520 and a Samsung Q6FN. You can listen to the noise when selecting tuner(no antenna) so I guess the speakers are correctly connected. I connected the HDMI to ARC HDMI out of the tv with the TV input of the amp. I change the settings to the tv sto the sound is transimitted through HDMI instead of tv speakers. I reset the amp to factory settings. The link to amp's manual is: https://www.pioneerelectronics.com/StaticFiles/Manuals/Home/VSX-520_OperatingInstructions0302.pdf HDMI keeps flashing Any advice please?
