Title:
pulseaudio doesn't detect (new) USB headset
Status in alsa-lib package in Ubuntu:
Confirmed
Status in pulseaudio package in Ubuntu:
Confirmed
Bug description:
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?
