Your quest is thankfully unrelated to ARC/CEC.

Find a tiny TPA3255- or TPA3116-based amp. These are class D amplifier chips made by TI.

Buy one of these from e.g. Amazon.

Optionally: Throw away/recycle away the supplied chinese noname power supply. Buy a used laptop PSU from a reputable brand locally for cheap instead. I scored a Lenovo 135W/20V laptop PSU for $5 at my local Goodwill equivalent. Solder on a 5.5mm barrel jack connector.

My fav for your use case: Fosi Audio TB10D.

1. His speakers are powered already. He doesn't need an amp. 2. Even if they weren't, how is he supposed to connect to the Fosi without a headphone jack coming out from the TV? The Fosi only has RCA input.

1. That information just arrived as a reply to my comment.

2. "Luckily, I have one of the last remaining TVs with a headphone jack."

I'm using active bookshelf speakers with integrated amps. They are working fine.

I really dislike this behavior. You presented a problem, but you didn't want a solution. You wanted attention.

I do want a solution. You haven't provided one.

You suggested an amp. The fact that I'm able to use a headphone jack to connect my speakers should tell you I don't need an amplifier. The question posed is how to connect those speakers if I no longer had access to a headphone jack. Currently the headphone jack is working fine.

For what it's worth, here's a comment that seems like it's get a perfect solution for me.

Sorry if I was unclear.
