Audiocast Firmware

Where to find those firmwares

While browsing online ressources, I found a presentation by 'exploiteers' hackers Exploiteers-DEFCON25.pdf. In this pdf they mention that Linkplay manufacturer provides a whole bunch of OEMs with their audio over wifi chipsets, and they give us a link to their firmware repository: fwupdate.wiimu.com

Searching for our UUID (FF310001) gives us 2 sources of compatible firmwares:
- Muzo Coblestone iEAST/product.xml
- iEast / Audiocast a31imuzobox/product.xml

Digging

- In the Muzo folder you will find v3.6.4007 released on 2017/01/07, you can install it with the help of the web interface and it works just fine. BTW this means the version recently announced on Muzo's website is actually one year older than what they claim.
- In the iEast folder you can find a slightly more recent v3.6.4107 released on 2017/02/07. This looks like the most recent official firmware for the Audiocast. I did notice a better audio quality than the stock 2016 firmware (no more random glitches) and smoother experience when steaming from Spotify.
