I have a home theater system but the problem that Amazon and Netflix deliver the sound through the browser only in stereo. My co-workers have recommended that I connect an Amazon FireTV stick to my Home Theater Reveiver because it transmits 5.1 audio tracks. Unfortunately, my receiver has only one HDMI output and no input. So that's flat. I do not have a TV, but a projector, which has only one HDMI input but the sound is flat. Currently I'm watching over the browser and the sound is transmitted in stereo via optical cable to the receiver.
Do you know devices that have an HDMI input, as well as an HDMI output and optical out? The corresponding device should logically handle FullHD and 5.1 sound.
The AmazonBasics Audio Extractor Converter would be an option
Do I understand this in the right manner:
You stream by computer (browser) movies from Amazon and Netflix.
On one HDMI output hangs your Beamer and per TOSLink goes the audio signal of the computer (PC, or laptop?) To the AV receiver.
At the computer you have basically just the speaker configuration of "stereo desktop LS" on "5.1 TOSLink", ie fiber switch.
However, a 5.1 signal is only transmitted if the video source delivers this signal (ready-made). Otherwise, only stereo (2.0) works.
Unless your sound card can create a 5.1 sound from all sources in real time ("live"). And that includes the "game sound".
But only the "better" sound cards can do that. Most "onboard" solutions are unable to do this.

But even a FireTV stick, or "full" FireTV can be used alternatively.
All you need is a suitable HDMI switcher:

You could connect three video sources (switchable) via a single HDMI cable to the projector.
And this device also has an audio extractor, which can then be used to send the TOSLink 2.0 to 5.1 signal to the AV receiver.
In the FireTV must then be switched only to 5.1 sound.
And the computer can be moved via the graphics card setting also for output of stereo and surround sound via the HDMI output (s.o.: "sound card"). For this special drivers were installed, unless they were manually deselected.
So you could then select the respective input signal at this switch and send the image to the projector and go via fiber optic to the AV receiver. The projector can also stay out and only the audio signal goes to the AV receiver.
I hope I have expressed myself halfway understandable.
