It seems like about half the time I boot up my PC, the PulseAudio plugin will display all of my audio devices only half the time. The ones that go missing are two USB audio devices: THR5 (USB speakers), and XIBERIA (USB headphones). This has been happening ever since I installed Manjaro a few weeks ago. Whenever it happens I’ve been restarting the computer and that usually fixes the issue.
I’m wondering if there is something I can do to get the USB devices to work without restarting the machine… Perhaps restarting some systemd service or something like that?
I should add that I tried the obvious: unplugging and plugging in the USB devices. This doesn’t work.
You can restart Pulseaudio with this command
systemctl --user restart pulseaudio
Is this system dual-boting with a Windows OS ? if so you should turn off their ‘fast boot’ - Intermittent problem - sometimes no sound after boot
Are USB devices plugged in to a USB 2.0 socket on system ?
USB Audio devices may not like using a USB 3.0 socket or USB hub
Unfortunately, that did not work. PulseAudio restarted but the audio devices still do not show up.
I am not dual-booting with Windows.
The headphones are plugged into a powered USB hub. The speaker is plugged directly into a USB 3.0 on the motherboard.
I just recently rebooted and the audio isn’t working again. I plugged in a flash drive to the USB hub and the drive did not blink like it normally does, and the drive does not show up in
Perhaps this is a USB problem, not necessarily an audio problem…
