Yamaha v667 problems getting sound from PC
I'm a new member, just bought, beginning to think unfortunately, a Yamaha v667. Previously had a Yamaha Stereo Amp & an Onkyo Sr505 both were great except the sound on the Onkyo rubbish compared with both the Yamahas.
However after spending a week with the new Yamaha am tearing my hair out & more because I find it impossible to get any sound out of it when connecting from my new Sony TV to my PC which has an ATI Radion 5450 HD card & integrated HD Sound Device. When connected to the 2 old amps worked perfectly but no go with the 667.
I am in contact with Yamaha but they just keep referring me to the manual, which although quite good has no mention of connecting to the PC?
I tried it with my HDMI TV cable connection, 3 different cables, also via Audio 1 & 2. The problem with Audio 1 & 2 is although I get the sounds it defaults to the Yamaha screen saver & with the HDMI cable connected I just get the Monitor display. With both HDMI & Audio 1 or 2 connected I only get the picture, same if I disconnect the seperate Audio cables.
I have read somewhere that Yamaha recalled all 667's for other problems also, & Yamaha suggested I take it back to the dealer 45 miles away to get the software updated? As I've wasted so much time already if I take it back it will be for a refund not update.
Does anyone know the correct installation for a PC that has ALL my 30 years or so of music on the H/D, with this amp please or am I fighting a lost cause?
Thanks a heap.
