[SOLVED] Bluetooth headset microphone not detected

PulseAudio does not detect my bluetooth headset microphone.

Following PulseAudio/Troubleshooting arecord does not list any other microphone when bluetooth headset is connected.

arecord -l
----
**** List of CAPTURE Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC257 Analog [ALC257 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

I see no mention of microphone in the Bluetooth wiki nor the Bluetooth Headset wiki.

I have the same problem. Works fine on my mobile phone but not on Archlinux laptop. I'm using Sony WI-1000X.

Re: [SOLVED] Bluetooth headset microphone not detected

arecord is not supposed to show you anything it will  be a pulse device, the default will generally be the microphone-less but higher quality a2dp protocol. You should be able to switch that under the Configuration tab in pavucontrol (or similar facilities of whatever mixer) in doubt post

pacmd list-cards
pacmd list-sources

Re: [SOLVED] Bluetooth headset microphone not detected

pavucontrol worked and led me to the command line solution.

1. List cards to find the card name and available profiles

pacmd list-cards

2. Enable the mic by selecting the HSP/HFP profile

pacmd set-card-profile <card-name> headset_head_unit

3. Alias

earmic()
{
    if [ "$1" = "off" ]; then
        profile="a2dp_sink"a
    else
        profile="headset_head_unit"
    fi

    pacmd set-card-profile <card-name> $profile
}

Marking as solved. Thanks V1del!

https://www.freedesktop.org/wiki/Softwa … Bluetooth/

The "auto_switch" option of module-bluetooth-policy got a new mode: mode "2" can be used to enable automatic profile switching from A2DP to HSP when a recording stream appears without any role set.

How have you got this solved?

It's better if you explain it step by step
