I have an issue on Ubuntu 22 with JBL Headphones: JBL Quantum 610 Wireless - wireless no sound only microphone Subjectively it is closely related to this issue JBL Quantum 610 wireless connection problem

However the suggested solutions are usually upgrading the kernel.

That is something unthinkable for me considering a focus on LTS versions.

So let me ask more general question:

If there's a device listed in aplay -l but it is not shown in the classic Settings => Sound => Output => Output device - can one force Ubuntu into sending the output signal into some hardware device using terminal?

  • You can certainly upgrade the kernel on an LTS version. Your question does not say you are running LTS it is the version number of Ubuntu Core. – David Mar 27 '23 at 13:26
  • PS : I can partially get closer with `alsamixer` where I can choose the target sound card, but then I can't adjust the volume @David that is irrelevant to this issue though (and I did not say you coudn't, just that it's unacceptable for me, since I assume LTS is mainly tested with the expected kernel) – jave.web Mar 27 '23 at 13:32
  • @Rinzwind Thanks, but pipewire doesn't work at all, `pavucontrol` I already tried - doesn't show, only thing that shows it somehow is `alsamixer` which sadly can't adjust the volume. – jave.web Mar 27 '23 at 13:36
  • An LTS is tested and works with many kernels. – David Mar 27 '23 at 14:42
  • @David I wanted to be sassy, I won't. Many may be but not all. E.g. yesterday we've tested with kernel 6.2.8 and it does not load ... My bad is I though it's being replaced, but there's rather a choice to choose from all installed kernels. So I could later fallback to the one I know works. Still, not the point of this Q :-) – jave.web Mar 28 '23 at 08:15
  • No 6.2 kernel is a supported kernel for Ubuntu at this time so no it has not been test. I was referring to supported kernels. – David Mar 29 '23 at 08:03
  • @David oh, ok, in that case it was just a misundestanding :) – jave.web Mar 29 '23 at 08:23
