@Marco and Hui Wang My Dell Latitude 5411 also contains an Intel BT Module 8087:0026. I can also reproduce the problem with my Sony WH-CH700N headphones. A2DP is fine, HSP/HFP is broken.
I also tried Marco's fix and copied the newer firmware (https://launchpad.net/ubuntu/+source/linux-firmware/1.190) for ibt-19-0-4, but just like Hui Wang the problem still exists. I can also confirm the hciconfig behaviour, every time I switch to HSP/HFP, the TX sco counter increases by one, but the RX sco counter stays at 0. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1871794 Title: [Bluetooth] No audio output/input in HSP/HFP mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1871794/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
