The cast firmware is still at 1.36 whereas the other Cast devices like Nest devices are at 1.46. When will this device be updated to the latest cast firmware?

Asked by: OmBheemBush
If its ROKU NO SO IM NOT ABLE TO SPEAK OF SMART TVS COME WITHOUT ROKU. I own a 4k room smart TV and YOU ARE FORCED TO BUY ROKU PRODUCTS YOU CAN NOT SET UP ANYTHING THAT ISNT ROKU. I OWN THIS and the Roku tv not compatible. I love this speaker in wish I could carry it around since its not really made to be portable. Like the cylinder shaped JBL devices. There is also a Walmart brand ONN soundboard that comes with ROKU SO IT CAN BE USED WITH THE ROKU TO help with any confusion. You set up a TV using the Roku that comes installed on Walmart ONN soundboard.

Hi, are there any updates to the firmware that make it compatible with Airplay 2? or 1? What's its latest firmware update and is there an online link showing what the updates are about? Thanks.

Asked by: kimos
Hi, I tried the provided link and all I got was this error: 404 - Page not found at the JBL support site; the questions are simply and shouldn't need further information: does it support Airplay via firmware update, what's the latest firmware update and what does it contain; I'm guessing JBL might publish them as this is common practice. Thanks.
