for everyone stranded when Google pulled the plug

An alternative to Chromecast Audio.

Google discontinued the Chromecast Audio in 2019, and every replacement costs more than the $35 dongle ever did. Home Audio Sync brings back synced, multi-room audio using the phones, tablets, laptops, and receivers you already own — no dongle to hunt down.

Chromecast Audio cost?

The dongle is discontinued, so “replace it” now means new hardware. Drag for the number of rooms you want to fill, and we'll price the modern Wi-Fi streamers you'd buy to get casting back — against Home Audio Sync, which needs none.

02 — What the discontinuation left behind

Five reasons the gap
still stings.

The Chromecast Audio was a $35 miracle. Here's what its discontinuation left behind — and how Home Audio Sync fills the same gap.

Discontinued 01

Google stopped making it in 2019.

You can't buy a Chromecast Audio new anymore. Owners are paying inflated resale prices for a five-year-old dongle just to keep a multi-room setup alive. Home Audio Sync needs no dongle at all — the devices you already own become the endpoints.

Support winding down 02

One OS update from going dark.

A discontinued product doesn't get fixes. Every Android, Google Home, or Cast update is a chance for something to break with no patch coming. Home Audio Sync is a web app — it's actively maintained, and it runs in any browser you already have.

Replacement cost 03

Every modern replacement costs more.

The cheapest like-for-like Wi-Fi streamers start around $90 and climb past $400 for line-out models — per room. A four-room setup that cost $140 in Chromecast Audios now runs several times that. Home Audio Sync is $0 in hardware.

Cast lock-in 04

You depend on apps supporting Cast.

A Chromecast Audio only plays what an app chooses to cast to it. When a service drops Cast support, that room goes quiet. Home Audio Sync plays your own library and YouTube directly in the browser — no app has to cooperate.

One more dongle per room 05

Another thing plugged in to fail.

Every Chromecast Audio was one more device drawing power, holding a cable, and eventually dying. Home Audio Sync turns the hardware you already keep charged and updated into the speaker — nothing new to plug in.

04 — Why we built it

A note from the person who built this.

I've wanted a whole-home audio setup for years, but I couldn't justify spending thousands of dollars on proprietary hardware. I had speakers in my office upstairs, a receiver on the main floor, and surround sound in the basement — and I just wanted a way to use them all together.

There had to be a way to use the old phones, tablets, and laptops I already had lying around. So I built one. It's a web app — you open a room, drag in your music, and scan a QR code on any other device to lock it into the same audio stream. No apps to install, and nothing to discontinue out from under you. It plays directly through the browser.

Getting the synchronization right was the hard part, and there are still rough edges — TVs and Bluetooth devices are tricky. But for anything that loads and plays quickly, it's seamless. It's mostly for listening to your own music, with YouTube integration for tracks you don't own.

05 — Common questions

Questions Chromecast Audio owners
are asking now.

You can — they keep working as long as Google keeps casting alive. But the point of Home Audio Sync is that you don't need them: any phone, tablet, laptop, or TV becomes a synced audio endpoint through the browser, so you're no longer dependent on a discontinued dongle.
The Chromecast Audio fed your existing hi-fi through its line-out, so the quality was really your amp and speakers. With Home Audio Sync, plug a laptop or phone into that same amp via its headphone jack or a cheap Bluetooth receiver and you get the same result — the audio quality is decoupled from any single dongle.
Within a few tens of milliseconds — close to perceptual perfection for music. TVs and Bluetooth speakers add their own latency and are the hardest case; phones, tablets, and laptops on the same network sync seamlessly.
Casting from apps was the Chromecast Audio's signature feature. Right now Home Audio Sync is built around your own library plus YouTube; native app-casting integrations are on the roadmap but involve licensing and technical hurdles outside our control. If you mostly play your own collection — or use YouTube — you're good today.
