2011 GX 460 sound problem
 

When you start the car if you hear a small pop sound the speaker system will not work. Radio nor bluetooth speaker for my phone. If you turn the car off and restart it and do not hear the pop sound then you have sound. Sometimes you will have to do this three or four times before you have sound. Any ideas or suggestions from my fellow Lexus owners ???? I am new to this website as of today in hopes of getting a quick simple answer.
