There is a pretty old patch for PulseAudio that enables AptX: https://build.tizen.org/package/view_file/Tizen/pulseaudio/0020-add-bluetooth-a2dp-aptx-codec-support-samsung.patch?expand=1 It doesn't have the actual AptX library, which I guess cannot be distributed under the same license. We could perhaps have OPUS (which should perform quite well) instead which should be available in all distros already, that said no headset or phone would support it initially, though it wouldn't be a problem for phones to add support for it since it has been in use in WebRTC, youtube, skype, etc. > Regards > > Marcel > > -- > To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html -- Luiz Augusto von Dentz -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
