华为Freebude3麦克风在Ubuntu18.04上不工作

Question

我正在运行Ubuntu18.04，我试图通过蓝牙使用华为Freebuds3。

我没有问题，在配对和输出声音，但我不能使麦克风工作。

我检查了pactl list，这是输出：

Card #2
        Name: bluez_card.FC_94_35_BA_C6_A4
        Driver: module-bluez5-device.c
        Owner Module: 29
        Properties:
                device.description = "FreeBuds 3"
                device.string = "FC:94:35:BA:C6:A4"
                device.api = "bluez"
                device.class = "sound"
                device.bus = "bluetooth"
                device.form_factor = "headphone"
                bluez.path = "/org/bluez/hci0/dev_FC_94_35_BA_C6_A4"
                bluez.class = "0x240418"
                bluez.alias = "FreeBuds 3"
                device.icon_name = "audio-headphones-bluetooth"
        Profiles:
                a2dp_sink: High Fidelity Playback (A2DP Sink) (sinks: 1, sources: 0, priority: 40, available: yes)
                headset_head_unit: Headset Head Unit (HSP/HFP) (sinks: 1, sources: 1, priority: 30, available: no)
                off: Off (sinks: 0, sources: 0, priority: 0, available: yes)
        Active Profile: a2dp_sink
        Ports:
                headphone-output: Headphone (priority: 0, latency offset: 0 usec)
                        Part of profile(s): a2dp_sink, headset_head_unit
                headphone-input: Bluetooth Input (priority: 0, latency offset: 0 usec, not available)
                        Part of profile(s): headset_head_unit

我曾试图将Free之母的配置文件(例如，从Blueman )更改为headset_head_unit，但是我无法这样做，而且从/var/log/syslog中，我可以看到的唯一相关错误是pulseaudio[3175]: [pulseaudio] module-bluez5-device.c: Refused to switch profile to headset_head_unit: Not connected，即使设备连接了。

有人能帮我吗？

显然，这里的问题是华为的FreeBuds 3不支持耳机配置文件。他们只支持免手配置文件(HFP)，这可以在蓝牙can输出中看到。另一方面，PulseAudio不支持开箱即用的HFP，如下所述：https://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/Bluetooth/

因此，唯一的选项是安装和安装oFono，或者自己修补和编译PulseAudio。修补程序可在这里获得：https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/merge_请求/94
