Public bug reported: When booting the system (Lenovo Thinkpad L480/L490), all connected USB headsets are recognized and can be used, and configured via pavucontrol.
When hot-plugging the USB headset, either the speaker is recognized, or the microphone, rarely both. But when both are recognized, the microphone is always a "multichannel" device. When both the speaker and the "multichannel" microphone are recognized, only one can be used - either speaker or microphone. When selecting the speaker, the microphone is switched back to any other device available, them same goes for the microphone and the speaker - any other speaker is selected. A workaround is to plug in the USB headset and run "pkill -U $USER pulseaudio". Everything works fine until the next hot-plug (eg. a second headset). Running "lsb_release -a" gives No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 18.04.4 LTS Release: 18.04 Codename: bionic Attached is the output from "ubuntu-bug pulseaudio". Currently 10 % of our users are affected by this bug, all running the same Ubuntu and package versions. I activated the proposed repository to check if any updates available fix the problem, but to no avail. I also switched kernels (from 4.15 to 5.5 mainline from https://wiki.ubuntu.com/Kernel/MainlineBuilds). I read bug #1325282 (https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1325282) and it sounds somewhat very familiar, but instead of "env={}" in /usr/share /ubuntu-drivers-common/detect/sl-modem.py there's "env=env". Removing "env=env" doesn't resolve the problem. Do you require additional information? ** Affects: pulseaudio (Ubuntu) Importance: Undecided Status: New ** Attachment added: "pulseaudio.info" https://bugs.launchpad.net/bugs/1865499/+attachment/5332737/+files/pulseaudio.info -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1865499 Title: pulseaudio doesn't detect (new) USB headset Status in pulseaudio package in Ubuntu: New Bug description: When booting the system (Lenovo Thinkpad L480/L490), all connected USB headsets are recognized and can be used, and configured via pavucontrol.
