我使用 (k)ubuntu 工作,现在我必须每天使用视频通话应用程序,我注意到我的集成麦克风质量不佳。我知道我的蓝牙耳机可以用作耳机,因为我在手机上将它用作蓝牙耳机,它甚至在音量混合器中显示为耳机。当我将耳机连接到我的电脑时,我可以使用 a2dp(立体声播放),但不能使用我的麦克风。当我尝试在 pulseaudiovolumecontrol 中切换到 hsp/hfp 时,我可以听到我自己的声音在我的耳机中回响,但我再也听不到来自我的电脑的任何声音。但是,我可以在音量管理器中看到麦克风现在可用(尽管它不起作用)。以下是有关我的硬件的一些详细信息:
根据 lspci,我的 wifi/bt 卡:
3b:00.0 Network controller: Intel Corporation Wi-Fi 6 AX200 (rev 1a)
PACMD 输出:

现在还查看我的日志以查找与蓝牙相关的错误,我看到一些引起问题的行:
Unable to get io data for Headset Voice gateway: getpeername: Transport endpoint is not connected (107)
Failed to release transport
/org/bluez/hci0/dev_FC_58_FA_C4_9D_17/sep1/fd7: Method "Release" with signature "" on interface "org.bluez.MediaTransport1" doesn't exist

更新:我尝试更新到 groovy gorilla,因为我认为它可以解决我在https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1871794中所述的问题, 但它没有解决,所以我将标题更新为 20.10
