Hi, Here are "few" patches which at the end of series add aptX support to BfA. Of course, since aptX is a proprietary codec, this is only wrapper around encoder library which has to be provided by platform vendor since it needs to be licensed. Once one has library, aptX can be enabled in following way: adb shell setprop persist.sys.bluetooth.codecs aptx adb shell setprop persist.sys.bluetooth.aptxlib <aptx-library>.so Note that this works with headsets which have aptX codec registered as 0x0000004f/0x0001 vendor specific codec info which seems to be most common. However, there is (are?) headset like Kinivo BTH410 which claims aptX support but has only SEP with vendor codec 0x0000000a/0x0001 which does not seem to be compatible with first one. It won't work. Apart from many fixes and aptX support, this patchset also adds definitions and tools support for AAC. No codec support in HAL audio yet, this is wip at the moment - there is AAC encoder available in AOSP which can be reused here. And no pass-through for AAC since it does not seem to be possible, at least not at the moment.
