My TV and the HDMI cable are ARC compatible.
I found out that the speaker was on mute hence the speaker icon, so please ignore that aspect.
Please, advise me on how to use the Straight button to get 2 channels as nothing happens when I press the button.
Can you bring the GUI menu up on your TV? You must do this first.
Now go to audio/speaker set up.
Tell the receiver you are just using two speakers.
Now see if you can get the set up test tones to play through your speakers.
If you can no go to the input set up menu and configure the inputs correctly for what you have.
ARC can be difficult to set up. Disabling CEC often helps.
I think part of your problem is looking for buttons.
Modern receivers set up by navigating set up GUI interfaces on the TV screen.
Forgive me, but you seem to be unusually technically challenged when confronted with modern AV gear.
We will do our best to help.
I have to go to our Eagan residence now for Easter.
Later I will download your manual and see if we can talk you through it.
What is your TV? I will find that manual as well.
It is possible you will have to get someone on site with you.
Unfortunately you are not alone having these kind of issues. This is something that could and needs to be corrected to make units more plug and play like times of old. This would require cooperation from lots of parties to get done, and I'm not optimistic this will happen.
This is causing sales resistance I believe and driving significant consumers away.
We will do our best, but lately we have unfortunately been unable to help some.
My fear and others, is that there are going to be more than a few people we can not bring up to speed for the times we live in. These issues are the least of them. I fear we are approaching a time where substantial numbers of people will be unemployable. That is going to be the big issue we have to confront.
I'm aware of more than a few cases personally. My son is head software engineer of pretty large outfit. Now when asked what he does for a job, he cynically says "I put people out of work." Unfortunately it is true.
