Re: Does HDMI Video signal cancel other audio?
Which Onkyo receiver do you have? Are you using a 5.1 speaker system through your Onkyo? Or do you just want 2-channel into your RPTV? Does your RPTV accept audio over HDMI?
You can have HDMI deliver picture to your TV and then select in your player's output settings to not use HDMI audio out. Instead use the Toslink or Digital Coaxial output of your player into your receiver and set your receiver to read the desired audio connection on whichever setting you want. You might need to adjust the delay settings of either your player's video output or your receiver's audio output to correct any possible sync issues.
