Hi all, I'm using openSUSE 15.5 (KDE) along with some bluetooth headphones. From what I could see, only the default SBC is used as an A2DP audio codec, despite the headset supporting more codecs. Please check the following (trimmed) output: ~ # pactl list Sink #2 State: RUNNING Description: WH-1000XM5 Driver: module-bluez5-device.c Sample Specification: s16le 2ch 44100Hz Owner Module: 25 Latency: 60263 usec, configured 45317 usec Flags: HARDWARE HW_VOLUME_CTRL LATENCY Properties: bluetooth.protocol = "a2dp_sink" bluetooth.codec = "sbc" device.description = "WH-1000XM5" device.api = "bluez" device.class = "sound" device.bus = "bluetooth" device.form_factor = "headset" bluez.class = "0x240404" bluez.alias = "WH-1000XM5" device.intended_roles = "phone" Porto: headset-output: Headset (type: Headset, priority: 0, available) ~ # avinfo XX:XX:XX:XX:XX:XX Connecting ... Stream End-Point #1: Audio Sink Media Codec: SBC Channel Modes: Mono DualChannel Stereo JointStereo Frequencies: 44.1Khz 48Khz Subbands: 4 8 Blocks: 4 8 12 16 Bitpool Range: 2-53 Content Protection: SCMS-T Stream End-Point #2: Audio Sink Media Codec: MPEG24 Object Types: MPEG-2 AAC LC Frequencies: 44.1kHz 48kHz Channels: 1 2 Bitrate: 320000 VBR: Yes Content Protection: SCMS-T Stream End-Point #3: Audio Sink Media Codec: Vendor Specific A2DP Codec Vendor ID 0x0000012d Vendor Specific Codec ID 0x00aa Vendor Specific Data: 0x3c 0x07 Vendor Specific Value (LDAC) Frequencies: 44.1kHz 48kHz 88.2kHz 96kHz Channel modes: Mono Dual Stereo Content Protection: SCMS-T Now, despite these headphones not supporting any of the aptX codecs, it would be a nice option to be able to at least enjoy one of the other codecs, namely LDAC, but AAC would be a welcomed addition too, and likely preferable in many situations too... It's been quite some time since I've dug this, just to remember that BT Profiles/Codecs are not a straightforward subject. Despite this, I was quite surprised that it is substantially better than a few years ago. In addition to the codecs, there's also the sound stack bluez/pulseaudio/pipewire/more (?) options... Then there's the plugins/bt_modules/more (?), I can see that I do have some bt modules on pipewire: ~ # rpm -ql pipewire-spa-plugins-0_2 | grep bluez /usr/lib64/spa-0.2/bluez5 /usr/lib64/spa-0.2/bluez5/libspa-bluez5.so /usr/lib64/spa-0.2/bluez5/libspa-codec-bluez5-aac.so /usr/lib64/spa-0.2/bluez5/libspa-codec-bluez5-faststream.so /usr/lib64/spa-0.2/bluez5/libspa-codec-bluez5-ldac.so /usr/lib64/spa-0.2/bluez5/libspa-codec-bluez5-opus.so /usr/lib64/spa-0.2/bluez5/libspa-codec-bluez5-sbc.so /usr/share/spa-0.2/bluez5 /usr/share/spa-0.2/bluez5/bluez-hardware.conf Now, for the real question(s): How can I make use of any other code with openSUSE 15.5 and KDE? Some maybe useful data: - openSUSE Leap 15.5 upstream, fully updated - This install is an upgrade from several Leap's before 15.5, hopefully done right (I've tried this on different versions too) Also maybe I have an unsupported combination of all this?! I really can't tell at this time! Feel free to also direct me to reading materials as I'll gladly go through them. Also feel free to ask for more information on my system if you believe it's relevant. Thank you all for your help! Regards, -- Rui Santos Veni, Vidi, Linux

Hi, Thank you for your reply Masaru. Just for the record, to help someone else that requires a tldr solution, I've followed this guide: https://en.opensuse.org/openSUSE:Pipewire It basically requires one to switch from PulseAudio to Pipewire. Those basic install and reboot steps worked perfectly! I can now use all AAC and LDAC codecs too. I can even use mSBC for Headset, which is quite some progress too :) Thank you!

The only thing excluded in openSUSE is aptx.
