我从 18.04 升级到 20.04 现在我没有蓝牙工作并且集成音频从脉冲音频输出列表中消失了

  • 772

我最近从 Ubuntu 18.04 升级到 20.04，所有蓝牙设备和主板集成音频都停止工作。

我的集成主板声卡 Intel PCH 也从 Gnome 声音列表中消失了，现在我只看到 HDMI（我的显示器），但在 alsamixer 中我也看到了我的 Intel PCH。

首先，我喜欢解决这个蓝牙问题。Intel PCH 无关紧要，我很少使用非BT 耳机。

当我重新启动系统时，从 vm/de 注销 Gnome 将处于飞行模式，如果我运行它不会生效： sudo systemctl enable blutooth

我也尝试过使用 lxde，但存在相同的蓝牙问题和集成音频问题。

USB音频似乎工作正常。

我升级了内核（没有效果）：

我已经尝试过这些解决方案，但它们似乎对我不起作用：

  1. 我遇到了蓝牙硬件问题。这只是有时会发生。就我而言，蓝牙坏了，当我升级到更新的操作系统时，可能会得到一些电动长矛或类似的东西。

    我购买了新的加密狗，当将加密狗连接到 USB 端口时，Gnome 立即显示蓝牙已开启。

  2. Best Answer

    我的耳机也能用

    我编辑了这个文件/etc/pulse/default.pa 并改变了

    ### Load audio drivers statically
### (it's probably better to not load these drivers manually, but instead
### use module-udev-detect -- see below -- for doing this automatically)
#load-module module-alsa-sink

    对此（评论 alsa-sink

    ### Load audio drivers statically
### (it's probably better to not load these drivers manually, but instead
### use module-udev-detect -- see below -- for doing this automatically)
load-module module-alsa-sink

    并重新启动系统，我得到了 100% 的工作。
