Troubleshooting Netflix with my reciever, no sound

[Gil111000]

For reference, this is the back of your receiver:

Apparently this is how I connected the devices, I was mistaken above.

Cable box HDMI ARC >> Reciever HDMI 3
Reciever HDMI ARC >> TV HDMI ARC.
So the connections are not the problem..

Now my mom says each time she uses ths system, the reciever cuts out after a bit. I did buy it second hand but I wasn't aware of any problems with it. Maybe there's something fixable before I blame it on the seller...

When switching through music modes, like "2ch stereo" on the reciever, there's an audible click from the reciever. Then when switching back from this mode, another click. Only some make this click. Maybe it has something to do with it?

Would adding an optical cable solve this plonter?

I'm kind of lost here.

EDIT : The reciever now acts funny with the cable box too. It says it gets no signal from HDMI 2, while the cable box is connected to HDMI 3. It seems it only randomly works. When it doesn't, it gives no signal to the TV, and the reciever says "decoder off".

I did try to plug the cable box to HDMI 2, doesn't help. Still no signal.

Now I connected a laptop to the reciever instead of the cable box, and it sent picture and sound to the TV and the reciever said PCM.
When returning to the cable box, the TV 'dies' - TV screen is on, the cable box is on, but there's no signal on the TV. Receiver says 'decoder off'.

Maybe the cable box is faulty? Even though it's brand new. I can always contact the company. But if it seems like a reciever problem, I still want to troubleshoot it.

Ok, figured something was off from your original descriptions. Using a Samsung TV and Yamaha receiver with HDMI-CEC and ARC is a nightmare on a good day. It is a very unreliable setup and I can tell you from experience that even if you get it set up perfectly, it will cut out whenever it feels like it and have you unplugging HDMI cables and power cords to get it working again. A much more reliable connection for getting TV audio to the receiver is using an optical cable. But, before going on with any more instructions, I would urge you to get familiar with the receiver. You need to know more about what it does and how it does it so that you can get back to a particular setting if changed by accident. So, read over the manual and get that optical cable ready. In the meantime, the clicking sound you hear is the amp switching as you go from stereo mode to a surround mode. If you haven't already, go into speaker settings and set it to a two channel setup with no subwoofer.

Sounds like there's hope after all with the optical cable. I'll probably return home in the following days and try using an optical and direct the cable box's HDMI straight to the TV.

Is what you described a combination problem (Yamaha and Samsung)? Do any one here knows a similar problem with other recievers/TV's?

So the clicking noise is out of my worry list, that's good.

Now, when thinking about it, the optical cable will only serve media audio from the cable box, meaning when I do use Netflix, Spotify or whatever other audio source that isn't bound to the cable box, the sound quality won't even be slightly degraded, since the reciever and the TV are connected via HDMI arc. Am I missing something or does that sound correct?

The audio will be fine. You have some options with the cable box connected directly to the TV and other options with it connected directly to the Yamaha. If you happen to know the model of the cable box, that would help. As far as HDMI-CEC, there is absolutely no real standard that all manufacturers are bound to and they can call it what they want, in fact. With no standard, it's anybody's guess when connecting different devices from different brands. Samsung would be very happy if everybody who purchased one of their TVs also purchased one of their soundbars and doesn't really care if Anynet+ works when connected to other brands. If you connect the cable box directly to the TV, the audio from it as well as audio from the TV's Smart apps can be sent to the receiver via the optical cable after making certain settings.

A good thing to start with in using a used avr is to do a complete reset (microprocessor or factory reset it's often called). Then go thru setup.
