I have a Pioneer elite vsx lx 105 receiver hooked to my Samsung tv. The Roku stick is in the HDMI port for streaming on the Pioneer. It all works fine but I cannot control volume or muting from the Roku remote anymore. I turn on power with the remote and when i hit the home button it engages the receiver but all volume and muting has to be done with the receiver remote.
There was a post that suggested hitting the home button 5x, then FF, DOWN, REWIND, DOWN, FF to get to a menu which then suggested ;
choose RF remote menu
choose IR transmit menu
choose Enable Querying AVRs (instead of TVs)
Sadly, that did not do anything for my set up. Are there any other suggestions for allowing the Roku remote to control the volume/mute coming through an AVR like my Pioneer?
