We just bought a new Toshiba 39L1350U television and a Bose Solo speaker set.There are multiple HDMI connectors on the television. We hooked up the t.v. to the FIOS box via HDMI and had it in HDMI 1. The audio is hooked up via an optical cable. Everything works fine. Then to see how it would work (we're new at this stuff), we unplugged the HDMI from the FIOS box and plugged it into the HDMI on my wife's desktop pc and play some videos and that worked fine. So, we went out and bought another HDMI cable so we could use both the FIOS television signal and the PC when we wanted to watch videos etc. The FIOS is hooked up to HDMI 1 and the PC has a single HDMI cable going to HDMI 2. An optical cable connects the t.v. to the Bose Solo. When we decide to watch something from the PC and switch the t.v. input from HDMI 1 to HDMI 2 we get the PC video but no audio. Now here comes the weird part (at least to us novices). If we then disconnect the HDMI cable that was in number 2 and plug it into 1 or 3 and use the t.v. menu to select that input the sound will work. THEN, if we switch back to the FIOS via the input and go back AGAIN to the PC the PC will not have audio again. I don't know if I explained this very well, but I'm a so confused now it might not be very clear. Please ask if you need me to explain anything better. Thanks.
