为 Ubuntu Linux 开启蓝牙 APTX / LDAC 支持

一直以来阻止我购买蓝牙耳机的原因有一个,就是我的 Linux 笔记本不支持蓝牙 APTX,后来虽说什么索尼 LDAC 开源了,但是那群愚蠢的开源开发者们还在就“代码是否正统”在扯皮。

其实在 Linux 下支持蓝牙 APTX 与 LDAC 的协议进展一直有,有逆向工程的,也有整合代码的,但是都没有被 merge 到上游,因为他们还在扯皮。

而且现在 APTX 都已经被逆向工程了,LDAC 源代码都放出了,甚至都被 ALSA merge 了,pulseaudio 还没有动静,这不科学啊。

于是现在终于有国人行动了,我们感谢他。
