Code throughout the Android Open Source Project means that Android 15’s upcoming audio sharing function received’t be to be had at the Pixel 8a or older Pixel gadgets.
Audio sharing is a function that allows you to broadcast your telephone’s audio to close by gadgets that beef up Bluetooth LE Audio.
While the Pixel 8a or even Pixel 7 collection do beef up Bluetooth LE Audio, Google doesn’t appear to have plans to allow the needful broadcasting roles.
If you need to privately percentage no matter you’re being attentive to along with your close by buddies or members of the family, you usually want both an advanced wiring setup with splitters or everybody to have the similar emblem of software. That’s as a result of maximum cellular gadgets and wi-fi headsets that beef up Bluetooth don’t additionally beef up the usual’s LE Audio broadcasting function, which standardizes how gadgets broadcast audio to a number of close by gadgets over Bluetooth Low Energy.
While the most productive Android telephones in the marketplace already beef up LE Audio and are theoretically in a position to supporting its broadcasting function, it’s imaginable that now not each LE Audio-capable software will acquire broadcast beef up. Take, for instance, Google’s Pixel 8a and Pixel 7 collection. While those gadgets do beef up LE Audio unicasts — sending audio over Bluetooth LE to a unmarried headset — they’re poised to fail to see LE Audio broadcast beef up, consistent with an Android Authority research.
Earlier this yr, we shared a primary take a look at one of the thrilling new options of Android 15 referred to as Bluetooth audio sharing. Audio sharing is the user-facing identify that Google has given for Bluetooth LE Audio broadcasting, which is Auracast, as advertised via the Bluetooth SIG. The audio sharing web page in Android 15 makes it simple for customers to begin or hook up with an Auracast broadcast, nevertheless it’s most effective to be had on gadgets that beef up LE Audio pronounces. To check the function out, I had to allow LE Audio broadcast beef up manually on my Pixel 8 Pro in addition to allow Android 15’s audio sharing function. Then, I began a printed on my Pixel 8 Pro and hooked up to it the usage of a few of my Auracast-capable Samsung gadgets.
Enabling LE Audio broadcast beef up on my Pixel 8 Pro was once rather easy since the firmware beef up for it was once already there. In truth, all I needed to do was once set two machine houses — bluetooth.profile.bap.broadcast.lend a hand.enabled and bluetooth.profile.bap.broadcast.supply.enabled — to “true” for LE Audio broadcast beef up. These machine houses, respectively, allow the Basic Audio Profile (BAP) broadcast lend a hand position and supply position. The lend a hand position allows gadgets to find and hook up with Auracast streams, whilst the supply position allows gadgets to transmit Auracast streams.
Neither machine belongings is enabled via default on any Pixel software at the moment, together with the Pixel 8 Pro. However, when you assemble an Android construct for the Pixel 8 or Pixel 8 Pro the usage of the RELEASE_PIXEL_BROADCAST_ENABLED flag, then those two machine houses are routinely added and enabled. Notably, the software make-file for the Pixel 8a is lacking the conditional observation that inserts those machine houses. This doesn’t imply it could’t be added later, nevertheless it’s curious that it’s most effective lacking for the Pixel 8a and now not the Pixel 8 or Pixel 8 Pro.
To explain, I requested some assets if they’d any additional info to verify whether or not that is intentional or if it’s being added at some point. One supply shared that they noticed proof suggesting that Google intends for LE Audio broadcast beef up to be reserved for “main telephone[s]” within the Pixel lineup, which means that it’s deliberately being held again from the Pixel 8a. I reached out to Google to look if it might be offering a remark and can replace this newsletter with that observation if I pay attention again.
Withholding Bluetooth LE Audio broadcasting beef up from the Pixel 8a could be disappointing however in the long run now not sudden. After all, it wouldn’t be the primary audio-related function reserved for Google’s top rate telephones since spatial audio is significantly lacking on any A-series Pixel. Speaking of which, you’ll obviously see within the Pixel 8a’s make-file that, whilst the spatial audio machine library is integrated, the machine belongings that pronounces the software helps spatial audio is lacking, by contrast to the Pixel 8 and Pixel 8 Pro.
Device make-files are a good way to outline which information and houses to incorporate in an Android construct, so the truth that there’s no point out of the needful LE Audio broadcast houses within the Pixel 8a’s make-file suggests the function received’t be to be had at the software. We’re hoping this received’t be the case when Android 15’s audio sharing function ultimately launches, as it could be a bummer if most effective the Pixel 8, Pixel 8 Pro, and Pixel 9 collection beef up the function. Unfortunately, it’s imaginable the Pixel 7 collection received’t beef up the function both, as their make-files additionally don’t claim any LE Audio broadcast houses. Similarly, the Pixel 6 collection will indisputably now not beef up the function, as they don’t even beef up Bluetooth LE Audio.
