Im having a weird issue with my blu ray player and HT receiver. My set up: blu ray player (3D) panasonic DMP BDT 300, HT receiver Onkyo HT R540. I have a Yamaha speaker set (not sure about the model), I just have center, front and surround speakers and a subwoofer (no surround back speakers). For audio connection, I connected my Bluray player with the HT receiver with analog RCA audio cables using 7.1 ch analog output. My HT receiver doesnt have HDMI input, so I connect video (using HDMI output) directly to my TV), And thats the problem. I only get sound from center and front speakers, Im not getting sound from surround speakers. If I play the test tone with the HT receiver I get sound on evey speaker and subwoofer. If I play test tone with the bluray configuration menu, I only get sound in center and front channels. The same with movies, no sound using multichannel output, I changed the audio connection to optical (digital) and I get sound in everyspeaker. The problem just happens when I try to connect blu ray player to HT receiver with multichannel analog outputs. when I activate 7.1 analog sound with the bluray setup menu, I get the message "surround channel / surround back channel off" (or something like that). I almost got crazy trying to fix this issue with the blu ray setup menu, but dont get results. Im certain config is properly set, and the HT recever is put in multichannel, but cant get sound in surround speakers. Can anybody help me??
