why is my drivers speaker muted??

[MAXSPL_153]

he guys , i have a chinese puzzle on my hands. i have a panasonic cq-vd7500u h/u .. it plays just about everything fine all aux. inputs & vid inputs work great . but when i play a cd no matter if its a dvd , data disk , or a regular store bought cd the drivers speaker mutes . ipod , ps3 , satalite radio work fine on all speakers , it just when the h/u reads a disk the drivers speaker shuts off . iv googled my ass off and cant find anything that helps . nothing about it in the owners manual , and i cant find anything in the h/u menus about it. anyone know whats causing this , or how to fix this??

It's a DVD deck right?

Do the CD player change the setting to mulit-ch when it's in cd/dvd? If it changes to a 5.1 then you might have a processing issue. OR your drivers speaker may be part of the rear fill not the front left

Either way I would check what the sound setting are or change to when switching to cd, and to also make sure all your channels out are in the right spots

yea its a dvd deck . all outputs stay the same no matter what input im using . as does the audio codec. ive tryed to get into the menu options to see if there is something set to mute, but the ONLY damn thing i can find is the "NAV mute " function but thats set to "off" anyway . and all channel outs are correct . confusing huh ?
