This gives some hope that a fixed firmware wi= ll eventually be upstreamed on Linux. I replaced the fw with the MS version in your link and everything is mostly working now. The major problem I ran into with the updated firmware was aud= io dropouts using the A2DP AAC codec, but I switched over to SBC-XQ (even high= er bandwidth, funnily enough) by editing /usr/share/pipewire/media-session.d/bluez-monitor.conf and it's working flawlessly now. --=20 You may reply to this email to add a comment.
