Hello Pulseaudio-Mailing-List,
as in my answer stated here: https://askubuntu.com/questions/1261148/how-to-switch-my-phone-to-headset-audio-gateway-hsp-hfp-in-pulseaudio/1292524#1292524
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 indicator-sound-switcher to:
Input: Headset > FrontMicrophone
Output: Headset > Headphones
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:
Input: Headset > FrontMicrophone
Output: Headset > Headphones
when HSP/HFP gets activated. But I am not aware on how to achieve this.
Tested Setup:
- OS Ubuntu 20.04 LTS
- ofono installed.
- Android Galaxy S8+
- 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
Settings adjusted so far:
sudo vim /etc/pulse/default.pa
.ifexists module-bluetooth-discover.so
#load-module module-bluetooth-discover
load-module module-bluetooth-discover headset=ofono
.endif
sudo useradd -g bluetooth pulse
vim /etc/dbus-1/system.d/ofono.conf
<policy user="pulse">
<allow send_destination="org.ofono"/>
</policy>
Question:
How can one set Input and Output to FrontMicrophone and Headphones permanently for HSP/HFP Profile?
Thank you in advance for contribution to this issue.
Kind regards,
Raphael
