Afternoon all, I have an Onkyo TX-NR646 and use it to play my mp3 collection via a netbook running Kodi. The netbook is connected via HDMI and plays fine in Zone 1. I've just purchased some outdoor speakers (Yamaha NS-AW150) and want to hook them up as Zone 2 speakers (mainly to play the same music as Zone 1). Unfortunately I am having no luck at all getting any sound out of them (although they both work when tested as Zone 1 speakers). The speakers are connected to the Zone 2 speaker inputs and I've been into the receiver's setup menu to set them as Powered. I've realised that I can't get any sound from a HDMI connection out of Zone 2, so I have purchased an optical cable and have connected the netbook to Optical 1 (CD) on the back of the receiver. The netbook plays through the receiver on the STRM BOX HDMI input so I have gone into the receiver setup and set the Optical Audio input for STRM BOX to Optical 1. I've followed the instructions in the manual to get Zone 2 working (Zone 2 appears on the display on the receiver) and tried changing the input to STRM BOX (also tried CD).....doing this doesn't seem to change anything on the receiver display though? Nothing I do seems to get any sound out of Zone 2. Any ideas what I am doing wrong please? I got these speakers for my 50th birthday party next Saturday so I'm really keen to solve this before then. Thank you!
