From my understanding --enable-aptx and --enable-aptx-hd depend on https://github.com/Arkq/openaptx which states in the readme:
This project is for research purposes only. Without a proper license private and commercial usage might be a case of a patent infringement. So we can't distribute it in Debian or depend on it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2046047 Title: No aptX support To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bluez-alsa/+bug/2046047/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
