A friend of mine has an AC power to Ethernet adapter cable.
In unrelated news, he was once told that his employer would not replace the horribly out-of-date office printer until it was 100% unrepairably dead, and it mysteriously died a couple of weeks later.
Ah yes, IEEE 802.3HV.
When PoE just doesn't cut it

Can I get that with USB-C or do I need another adaptor? Thanks!
Is this from USB to gardenhose?! So I can finally connect my old thinkpad to the projector?!

In case you're wondering, some broadcast equipment, such as the Axia Radius, uses Ethernet sockets for the connection of balanced and unbalanced audio.
This simplifies cabling, but you need adapters at the end of each cable to go back to RCA, TRS, XLR etc.

Some networking equipment has serial ports (RS-232) that use RJ45 connectors. 3.5mm TRS connectors are also commonly used for serial ports.

How else did you think they got the dialup noises to play?
You could use it if you had another one with a female headphone jack. You could play your music to a speaker in another room if you have Ethernet in both rooms. Copper is copper.
I've done this. I've made speaker wire to ethernet adaptors to connect speakers in a different room through the walls to an amp. Feels and probably is so wrong.
It really depends how much power you put through the cable, ethernet is something like 0.2 mm2 per core. You'd definitely want to double up cores.
While, as you said, both wires will conduct electricity just fine, they will have different AC impedance.
I would guess this wouldn't make much of a difference if you go Audio->Ethernet->Audio, since sound is at fairly low frequencies. But Ethernet->Audio->Ethernet might have problems with really high data rates, like GiB/s.

Fun fact: usb uart to audio jack is actually a thing: https://ae01.alicdn.com/kf/HTB1G43QaOnrK1RjSsziq6xptpXaN/win8-10-android-mac-pl2303hxd-usb-uart-ttl-to-2-5mm-audio-jack-serial-adatper-cable.jpg
Some older android phones used the audio jack double duty as a serial debug console, the nexus 5 for example.

I totally used an adapter like that. It did have a raspberry pi in the middle, though.
I mean, the PinePhone has a switch to change the audio jack from audio into some kind of data transfer protocol. I guess someone could make it work.
I think you would need another connection (ie. a 3rd stripe, TRRS vs TRS cable) for data transfer. Although digital audio is all data anyways I guess and now I don't even feel right but I've already typed it out.
i made a male version of this 4 times and then bought a ABC RJ45 switchbox for my work desk, so i could choose between computer audio and desk phone audio and cellphone audio through my work headphones.. lets you bump your own music in between calls without dealing with pause buttons etc.. worked great.

ha! beat my Bluetooth network cable!
This is so you can record the dial-up sounds.
I mean, network cabling is the same unshielded twisted pair wiring we've used for analog telephone audio over the last 150 years.
Networking uses 4 wires in 2 pair for 10mbps and 100mbps. You need the full 8/4 for gigabit and above. Telephone uses 2/1.

It’s in this months Dongle Crate subscription shipment.
Btw, when do we get Micro Ethernet?
Ugh, micro Ethernet is a garbage standard. I prefer Ethernet Type C.
...for audio streams?
I mean, if the adaptor is active, this could actually work. I have a fucking USB-fed Router/Modem in a case this size.
Ah, I see you've worked telemarketing too.
TRS45
What part of the Apple store can I find this in?
HdbaseT audio only?
Is this a USB Ethernet adapter for one of those weird older devices that used 2.5mm for USB?
This is likely an adapter for a switch or router to access it's debug console.
