 +====== What? ======
 +Just some notes around the Sony WH-1000XM2
 +  * pro: wireless: bluetooth profiles for headset and High Fidelity playback (A2DP)
 +  * pro: quite good noise cancelling
 +  * pro: build in rechargable battery
 +  * con: when the cable is used, only headphone functionality is available. No microphone signal goes over the analog cable.
 +  * con: after 60min of wearing, I need to take the headset off

 +
 +====== Bluetooth profiles ======
 +As of Fedora34 with pipewire, following bluetooth profiles which are supported on Fedora34 can also be used with the Sony WH-1000XM2. First is the name as seen in 'pactl list cards', then a description.
 +
 +  * **These modes provide pure audio, and do not transport the microphone signal to the computer**
 +    * a2dp-sink: High Fidelity Playback (A2DP Sink), good audio quality
 +    * a2dp-sink-sbc: High Fidelity Playback (A2DP Sink, codec SBC), good audio quality
 +    * a2dp-sink-sbc_xq: High Fidelity Playback (A2DP Sink, codec SBC-XQ), better audio quality
 +    * a2dp-sink-aac: High Fidelity Playback (A2DP Sink, codec AAC), better audio quality
 +    * a2dp-sink-ldac: High Fidelity Playback (A2DP Sink, codec LDAC), best audio quality
 +  * **These modes provide audio + micro channel, so for example useful for chats and conferences**
 +    * headset-head-unit: Headset Head Unit (HSP/HFP), bad quality
 +    * headset-head-unit-cvsd: Headset Head Unit (HSP/HFP, codec CVSD), bad quality, 16KHz/16 bit
 +    * headset-head-unit-msbc: Headset Head Unit (HSP/HFP, codec mSBC), better quality, 48KHz/16 bit
 +
 +"Hands-Free Profile (HFP) Version 1.6 adds optional support for wide band speech with the mSBC codec, a 16 kHz monaural configuration of the SBC codec mandated by the A2DP profile." That is usable on Fedora34, it was implemented in Pulsaudio 15 and pipewire 0.3.23. For headset-head-unit-msbc, it might be required to modify a config file as follows:
 +<code>
 +$ mkdir -p /etc/pipewire/media-session.d/
 +$ cp /usr/share/pipewire/media-session.d/bluez-monitor.conf /etc/pipewire/media-session.d/
 +$ vi /etc/pipewire/media-session.d/bluez-monitor.conf
 +### set this:
 +bluez5.msbc-support   = true
 +bluez5.sbc-xq-support = true
 +</code>
 +[[https://www.commander1024.de/wordpress/2021/07/bluetooth-hifi-unter-linux/|details in German]].
 +
 +===== Fedora 34 and later / pipewire based setups =====
 +<code>
 +### Let's install the required packages.
 +$ sudo dnf install -y pipewire-alsa pipewire-pulseaudio pipewire

 +===== Errors & solutions =====
 +== Problem ==
 +  * 'blueman-applet' says when trying to connect to the headset "protocol not available.
 +  * bluetoothctl reports this:
 +<code>
 +[chris@電脳 ~]$ bluetoothctl

 +Attempting to connect to 70:26:05:9D:31:85
 +Failed to connect: org.bluez.Error.Failed
 +</code>
 +  * When trying to connect in 'blueman-applet', error "unknown protocol" appears, and "systemctl status bluetooth.service" reports:
 +<code>
 +bluetoothd[23]: src/service.c:btd_service_connect() a2dp-sink profile connect failed for 70:26:05:9D:31:85: Protocol not available
 +bluetoothd[23]: src/service.c:btd_service_connect() a2dp-sink profile connect failed for 70:26:05:9D:31:85: Protocol not available
 +</code>
 +== Solution 1 (pulseaudio based setups only) ==
 +  * Ensure package pulseaudio-module-bluetooth-freeworld or pulseaudio-module-bluetooth is installed.
 +  * If you installed the package after starting pulseaudio or your Xorg session, then do this as user:
 +<code>
 +killall pulseaudio
 +pulseaudio --start
 +</code>
 +== Solution 2 ==
 +Install package blueman and run 'blueman-manager', for me that frontend was able to connect when 'bluetoothctl' could not.
