Ubuntu 20.04.3 间歇性蓝牙连接

我遇到了间歇性的蓝牙连接问题，我可以在启动时连接设备，但过了一段时间（30 分钟）后，连接就会降级（跳线/抖动）。如果我断开设备连接并尝试重新连接，blueman-manager我会遇到以下两种情况：

  1. 成功连接后，设备不再被列为输出pavucontrol
  2. 连接错误：Connection Failed: Resource temporarily unavailable

尝试的解决方案

  1. 取消配对/修复设备
  2. 重置 pulseaudio 配置（https://askubuntu.com/a/875891/1569612）
  3. 重新启动 pavucontrol ( pulseaudio -k) 或重新启动蓝牙 ( systemctl restart bluetooth.service)
  4. 尝试重新加载 pulseaudio-discovery 模块（https://askubuntu.com/a/1062044/1569612）以上产生以下错误
taylorswift2018@box:~$ pactl load-module module-bluetooth-discover
Failure: Module initialization failed
  1. 在 x11 之后加载 pulseaudio (https://askubuntu.com/a/689297/1569612）

输出systemctl status bluetooth.service

答案1

在尝试了 gnome 驱动程序面板中的开源驱动程序后 駕駛面板仍然看到问题，我决定自己构建和更新驱动程序，因为我相信apt这个包的版本已经过时了。使用下列的远程和指令以及重新启动恢复了一致的蓝牙行为

编辑：没有，我已经放弃了，并决定不使用无线作为解决方法，因为我已经在这些垃圾上浪费了足够多的时间。
