Connect TV to av receiver, and then connect the av to DVD and Bose sound system

[Tvuj]

I have connected everything as per the manual instructions but I have no sound. There was no sound also when the speakers were not connected yet.
I have a hdmi cable from the TV to the av. Then the av is connected to the Bose system with an optical cable, and the av and DVD are connected with another hdmi cable.
Is it a connection problem or is there something wrong setting wise??

Is that optical port an out? It is probably an in.

I'm assuming it's an optical out as there is only one port to connect to on the receiver

What is the model of the AV unit? Most models I see only have optical in (from the TV) and no optical outs

It is a Harman/Kardon AVR 151

There is also an second option to use a stereo audio cable but that still results in no audio

Check with mechanical there is an issue with audio cable.

So you are trying to send the audio to the Bose system correct? According to the picture of the back on this site http/eu.harmankardon.com/harman-kardon-product-detail_eu/hk-avr-151.html only connections actually labeled "OUT" are actually out the rest are in so that optical link can only receive an audio source not send it to another device.

The AV receiver is designed to pass through video and amplify audio.
The only audio outputs are the speaker connections.
You can't use an AV receiver as a switch to output to another amplifier.

To get sound from your TV through the HDMI cable you need to enable ARC in the telvision, which is probably only supported on one input.

If your Bose speaker system has an optical input it is self powered and cannot be connected to your HK receiver because it does not have optical out (only optical input).
If your TV has optical audio output you can connect the Bose directly to the TV. Connect the DVD to the TV via HDMI and you are done. If you want to use the receiver you will need to get passive speakers that would be powered from the receiver.
