16.04蓝牙耳机问题
16.04蓝牙耳机问题
提问于 2016-05-04 18:17:35
我最近从14.04升级到16.04。我的蓝牙耳机已经坏了。在过去的几个小时里，我一直试图诊断这个问题，但没有成功。我的蓝牙鼠标仍然连接正常。
Headset: Plantronics backbeat pro
USB Dongle: Asus - Broadcom BCM20702A0我有一个小问题，14.04，我必须包括"Disable=headset“在/etc/bluetooth/audio.conf，但似乎这个文件不再是访问的最新蓝光/脉冲音频安排。
我尝试过清除蓝牙，脉冲音频和蓝光，并重新安装，但没有成功。如能提供任何帮助，将不胜感激。

您可以从这里下载所需的文件。
在brcm/BCM20702A1-0b05-17cb.hcd中找到它，并将其放入/lib/firmware/brcm/BCM20702A1-0b05-17cb.hcd中。然后再重新插入蓝牙设备。dmesg将向您展示正确加载固件，这样您就可以使用Bluez软件配置蓝牙了。

问题的症结在于：
04-19:09:31内核:蓝牙hci0: brcm/brcm 20702a1-0b05-17cb.hcd的直接固件加载失败，错误为-2。
您的配置不适合此蓝牙适配器，因此它所需的固件将不会运行。没有固件它只是硅，它需要代码来正确地运行它，即固件。
这个链接应该有正确的固件，但它不是为独角兽之外的ubuntus打包的，所以您需要自己把它放在/lib/firmware/brcm/中
