<html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /></head><body style='font-size: 10pt; font-family: Verdana,Geneva,sans-serif'> Hello Pulseaudio-Mailing-List, as in my answer stated here: <a href="https://askubuntu.com/questions/1261148/how-to-switch-my-phone-to-headset-audio-gateway-hsp-hfp-in-pulseaudio/1292524#1292524">https://askubuntu.com/questions/1261148/how-to-switch-my-phone-to-headset-audio-gateway-hsp-hfp-in-pulseaudio/1292524#1292524</a> I do think me and many other Ubuntu users do suffer from an issue with HSP/HFP where one needs to manually change output and input device if Ubuntu used as Bluetooth Headset for Phone Calls and Playback. Clarification: A2DP Working fine: A2DP Media Playback from my Android Galaxy S8+ working fine. If i switch back from phone call to youtube the Profile A2DP gets activated automatically and audio is played out of my headphones on ubuntu. perfect. HSP/HFP Problem: Switching to a phone call results in automatic switch in pulseaudio (pavucontrol) => Configuration-Tab Device "Galaxy S8+" from "Off" or "A2DP" to "HSP/HFP" which is expected and perfect. But then there is no audio output nor audio input. One can see in pulseaudio that HSP/HFP gets activated. One can further inspect in pulseaudio that Input Device and Output Device for "Galaxy S8+" gets registered and shows as "Port: Phone". But audio is not working. If I than manually switch (while in a phone call) with the use of i<code>ndicator-sound-switcher to:</code> <pre><code>Input: Headset > FrontMicrophone Output: Headset > Headphones </code>then I can send and receive audio in this phone call nicely. Quality in HSP/HFP is not as good as A2DP but thats another issue I will try to fix elsewhere... So technically everything seems to work fine. But its very annoying while receiving or doing a phone call that audio input and output have to be set manually to FrontMicrophone and Headset Headphone. I do have multiple input and output devices and during a business talk or in a stressful situation it's not so easy to select the right devices fast and accurate. So I was looking for a solution to always set:</pre> <pre><code>Input: Headset > FrontMicrophone Output: Headset > Headphones </code> when HSP/HFP gets activated. But I am not aware on how to achieve this. Tested Setup:</pre> <ul> <li>OS Ubuntu 20.04 LTS</li> <li>ofono installed.</li> <li>Android Galaxy S8+</li> <li>Card #8 Name: bluez_card.88_75_98_9F_C3_35 Driver: module-bluez5-device.c Owner Module: 145 Properties: device.description = "Galaxy S8+" device.string = "88:75:98:9F:C3:35" device.api = "bluez" device.class = "sound" device.bus = "bluetooth" device.form_factor = "phone" bluez.path = "/org/bluez/hci0/dev_88_75_98_9F_C3_35" bluez.class = "0x5a020c" bluez.alias = "Galaxy S8+" device.icon_name = "audio-card-bluetooth" Profiles: a2dp_source: High Fidelity Capture (A2DP Source) (sinks: 0, sources: 1, priority: 20, available: yes) headset_audio_gateway: Headset Audio Gateway (HSP/HFP) (sinks: 1, sources: 1, priority: 10, available: yes) off: Off (sinks: 0, sources: 0, priority: 0, available: yes) Active Profile: off Ports: phone-output: Phone (priority: 0, latency offset: 0 usec) Part of profile(s): headset_audio_gateway phone-input: Phone (priority: 0, latency offset: 0 usec) Part of profile(s): a2dp_source, headset_audio_gateway</li> </ul> Settings adjusted so far: <pre><code>sudo vim /etc/pulse/default.pa </code></pre> <pre><code>.ifexists module-bluetooth-discover.so #load-module module-bluetooth-discover load-module module-bluetooth-discover headset=ofono .endif</code></pre> <pre><code>sudo useradd -g bluetooth pulse </code></pre> <pre><code>vim /etc/dbus-1/system.d/ofono.conf</code></pre> <pre><code> <policy user="pulse"> <allow send_destination="org.ofono"/> </policy></code></pre> Question: <pre>How can one set Input and Output to FrontMicrophone and Headphones permanently for HSP/HFP Profile?</pre> Thank you in advance for contribution to this issue.
