不能在HSP/HFP模式下使用蓝牙耳机- ubuntu 20.04
我有一个罗技无线耳机，可以工作在两种不同的模式:高保真立体声音频(A2DP)，没有麦克风和耳机(HSP/HFP)与微work。
A2DP模式可以工作，但是当我尝试切换到HSP/HFP时，耳机静音和任何背景媒体都会冻结，直到我回到A2DP。
这是我在切换模式时得到的dsmeg输出：

编辑：
ACPI错误可能是由驱动程序问题引起的。英特尔AX201卡是一个非常新的，系统没有正确地检测到它(正如我在这里中所要求的)。也许这些问题是有关联的。

我也经历过这个问题。有一个确认错误的脉冲音频和蓝光。请报告它对你的影响：https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1878194

在从19.10移到20.04之后，我正经历着同样的问题。
当蓝牙耳机被连接时，它被自动配置为HSP/HSP，但是它不能在这种配置下工作(在19.10中)。

我终于得到了我的蓝牙耳机工作在HSP模式，这意味着麦克风也工作。
第一步:确保您的蓝牙固件
当我执行命令时：sudo dmesg | grep -i bluetooth
我也收到了类似的信息：
蓝牙hci1: brcm/brcm 20702a1-0b05-17cb.hcd的直接固件加载失败，错误-2
在安装broadcom-bt-固件之后，返回相同的命令
21.883358蓝牙: hci0: BCM20702A1‘brcm/brcm 20702A1-0b05-17cb.hcd’修补程序
第二步:编辑/etc/脉冲/default.pa
并对模块(蓝牙)周围的ifexist和endif进行注释，从而自动执行策略和发现负载。
### Automatically load driver modules for Bluetooth hardware
#.ifexists module-bluetooth-policy.so
load-module module-bluetooth-policy
#.endif
#.ifexists module-bluetooth-discover.so
#load-module module-bluetooth-discover headset=ofono
load-module module-bluetooth-discover
#.endif第三步:清除和重新安装脉冲
我跟着这位
sudo apt-get --purge --reinstall install pulseaudio
并确保在/etc/pulse/client.conf您的autospawn = yes
比reboot
