Modern AV stuff is insane. I have no interest in taking it up as a hobby. I have an xbox, a TV, and a pair of bookshelf speakers. How am I supposed to get the audio to the speakers without a bulky expensive receiver box? Luckily, I have one of the last remaining TVs with a headphone jack. I don't use a remote for any of it. Side note: Sometimes the TV doesn't come on when you press its power button. After a tremendou…

A receiver has always been a pretty standard part of even really simple AV setups - you can get half decent ones pretty cheap, and then you just run either the HDMI ARC port or the optical/coax digital audio out from your tv to the receiver so that everything you plug into your tv has it's audio go out to the speakers.

Another infuriating issue is TVs with so few HDMI inputs. I have tried many different HDMI switchers and none of them work reliably, so it kind of puts me off of buying a receiver which would also have that function.

I’ve mostly had no issues with HDMI through Yamaha receivers and that includes weird things like an OSSC and Framemeister. On the other hand, HDMI switchers haven’t fared as well. I built a mini console rack with a switch and it doesn’t recognize several devices, even when manually selected.

> Yamaha receivers

In my limited experience, Yamaha handles HDMI-CEC significantly better than Denon/Marantz. As evidenced by the fact that I currently own a Marantz receiver and am reading this page, but back when I owned a Yamaha receiver, I had no need to care about all of this crud. Things somehow worked on the first try! I did not expect that. However, it conditioned me to expect that again with a different receiver (the sources and sinks are the problems, right? the receivers are super well tested because sitting in the middle and passing these commands around is their entire job, right? right?) which was a mistake.

(The actual issue with the Marantz is that it seems to be eating some kind of power-on command from the source, and not passing it on, so the TV never turns on if you try to turn on the receiver or the source. I have no idea how to fix this, short of following in the path of this article.)

I know I could do this. But I don't really have space for a box. And I'd rather not have it.

That little headphone jack is seriously driving bookshelf speakers to a reasonable volume? If it works it works but that doesn't sound right, unless these are actually self-powered speakers with their own amplifiers inside. I'd really like to know the details because this sounds crazy. Also, I collect a lot of old receivers and speakers. It's really not that complicated and the basics have been the same since the 70s…

The jack is not driving the bookshelf speakers. They're active. They have their own internal amps. It's simple if you use a receiver. If someone can point me to a receiver that's more like 4 inches than 18 inches, then I'd consider that a solution. Receivers are big boxes as far as I've seen. I don't have space. Or maybe I don't want to make space.

> It seems like AV stuff used to be so simple. > without a bulky expensive receiver box A "receiver" has been one of the standard options for making bookshelf speakers work for more than 50 years. A receiver is also not expensive. You can get a basic used one for under $100. I paid $30 for a perfectly working 5.1 Denon receiver with HDMI. Your problem is that you aren't even using "Modern" AV stuff. If you were, your…

Why are receivers so big? It's not exactly a money issue. I just don't want the big box.

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. https://en.wikipedia.org/wiki/Class-D_amplifier 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…

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

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.

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

"Media closet tour"

Just looks like a Rube Goldberg server to me. This is really illustrative of the nonsense that media copyright has manufactured. I'm not going to solve "HDMI-CEC weirdness with a XYX" I'm going to download the movie from a torrent or run an emulator.

Sonos makes this specifically. Has an RCA and HDMI input, along with being a Sonos device for streaming audio.

The only downside is the price.
