正如之前指出的，A2DP是单向的，每次需要使用麦克风时，您必须切换到HSP配置文件。但是手动操作并不理想，并且除非应用程序为流设置media.role=phone（大多数非VoIP应用都没有这样做），否则pulseaudio默认不会自动切换。
但是从Pulseaudio v. 11.0开始，可以在应用程序请求麦克风访问时自动切换配置文件，但默认情况下是禁用的。
/etc/pulse/default.pa中找到load-module module-bluetooth-policy行load-module module-bluetooth-policy auto_switch=2现在，每当应用程序请求麦克风访问时，pulseaudio将自动将设备配置文件切换为HSP，并在关闭流后将其切换回A2DP。
您需要重新加载pulseaudio模块以使更改生效：
pulseaudio -D时，出现了“E：[pulseaudio] main.c：Daemon启动失败。”错误。 - Yogi Katbasystemctl --user restart pulseaudio。 - backslashNsystemctl --user restart pulseaudio 失败，显示 无法重新启动 pulseaudio.service: 单元 pulseaudio.service 被屏蔽。 - Peter
虽然它不像安卓那样自动切换，但还是比待在巨无霸飞机仓库里要好一些！

The necessity to provide a modem to oFono makes the headset setup rather cumbersome. If you do not have a GSM/UMTS modem connected to your system (like in most desktop environments), you need a modem emulator. Unfortunately oFono does not allow to use a mobile (hfp modem, see below) as a modem to support headsets.
The best emulator choice is "phonesim" because there is a version that is maintained together with ofono. Most distributions contain a package ofono-phonesim or similar while the git version can be found at git://git.kernel.org/pub/scm/network/ofono/phonesim.git.
To set up phonesim, first create or edit the file phonesim.conf in /etc/ofono. It should contain the following lines:
[phonesim] Driver=phonesim Address=127.0.0.1 Port=12345Restart oFono and check with list-modems if the phonesim modem was found. Start phonesim with
ofono-phonesim -p 12345 /usr/share/phonesim/default.xml&The paths to phonesim.conf and default.xml might be different if you compiled ofono and/or phonesim from source. Now you can enable the modem either by using the enable-modem script or by issuing the following command:
dbus-send --print-reply --system --dest=org.ofono /phonesim org.ofono.Modem.SetProperty string:"Powered" variant:boolean:"true"list-modems should show that the modem is powered and online. If you want to play with the modem emulator, you can add the -gui option to the phonesim command. Then a GUI will pop up as soon as you enable the modem.
Once the modem is set up properly, you can connect your headset and the "Headset Head Unit (HSP/HFP)" profile should be available in pulseaudio.
