AVR-1909 no audio output

"Hi @geekittogether ,

Looking at the audio block diagram on p.32 of the service manual for your receiver, one common factor for no audio out from any digital or analogue audio inputs, is if it is setup to receive audio from EXT in

Here’s an image taken from the service manual that shows what I mean.

The orange arrow indicates audio received from digital sources e.g. HDMI

The blue arrow indicates audio received from analogue sources e.g. AM/FM tuner

The green arrow indicates audio from EXT in (external source?).

Since you are not getting any audio out from any digital or analogue audio input connection, it may be that the switch (Zone2 - SB assign?) shown by the multiple green arrows in the red box is set to ext and not to either ana or dsp.

There is also the possibility that the “mute” function may be operated, ;-)

Here’s a image taken from the troubleshooting section of the user manual that shows what to check if there is no sound from the speakers just to help eliminate other possible causes.
