无法在 HSP/HFP 模式下使用蓝牙耳机 - ubuntu 20.04

Question

我有一个罗技无线耳机，它可以在 2 种不同模式下工作：不带麦克风的高保真立体声音频 (A2DP) 和带麦克风的耳机 (HSP/HFP)。

A2DP 模式有效，但是当我尝试切换到 HSP/HFP 时，耳机会静音并且任何背景媒体都会冻结，直到我回到 A2DP。

这是我切换模式时得到的 dsmeg 输出：

Windows 10 双启动（禁用快速启动）

编辑：

ACPI 错误可能是由驱动程序问题引起的。intel AX201 卡是一种非常新的卡，系统无法正确检测到它（正如我在此处询问的那样）。可能是这些问题以某种方式相关。

我也遇到过这个问题。pulseaudio 和 bluez 有一个已确认的错误。请报告它对您的影响：https : //bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1878194
