I would like to report back that on Ubuntu 20.04 with Intel AX200 network card (8087:0029), I resolved this issue by following @Hui Wang's instruction
ibt-20-1-3.sfi and ibt-20-1-3.ddc from 20.10 driver HSP/HSF was greyed out before but is now available and functioning after powering off and on again. -- 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
