I'm having issues with two different brand new Yamaha Receivers. First i tried the RX-V773, returned it and got the RX-V475. Same issues. The sound volume is normal when i play net radio stations or airplay songs. But when i use switch to PS3 or Uverse box, the sound is extremely low. I using hdmi cables for everything. I have to crank up the volume to -20 db. Has anyone noticed this issue on Yamaha's?
