Oh! Was saying that it's lossy on Stock, non-existant on this ROM, Kiev Lineage Unofficial and was giving as much background/reasons as I could in hopes it would be implemented, possibly. My fault.@roiikka sorry, what model of earphone are you using? Your saying this is reproducable on stock, but works properly on other phones? Your mentioning AAC a lot, something that's inherently lossy. Viper4android is too. Idk, kinda lost. Maybe post a new logcat, preferably on lineage, so we can see what's happening?
I use the Sony Wi-C200 earbuds. They have amazing bass response on my S5, lossy-ish on Stock Kiev and it stays no HD, only APTX apparently here on these custom ROMs of the 5G Ace, Moto One. I get the infamous "greyed out HD" switch in dev settings. In Stock for the 5G Ace it has "disable AAC whitelist", you untick it, it says reboot, you do so and bam! HD AAC audio over bluetooth. No SBC needed. And APTX works. You guys want a logcat of that switch? I'd be more than happy to do so just say so and I'll get back on stock real quick. I'm on @SyberHexen s nice port of Havoc OS testi.g right now and same thing as his Lineage OS port but sticking with wired earbuds and seeing what you guys can do with this bluetooth thing.
Been seeing this thing about Sony needing to use LDAP or whatever it's called now, all this "contracts" smorgisporg. But it works on stock OS, like I said. It says "HD AAC", ya.
You guys want a log of that Disable AAC Whitelist switch ? **Standing by** ..
