Comment 34 for bug 1286021

I'm using Ubuntu 22.04.4 LTS.
I have a problem with 2.1 sound on Realtek High Definition Audio (2.1):

00:03.0 Audio device: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor HD Audio Controller (rev 06)
 Subsystem: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor HD Audio Controller
 Kernel driver in use: snd_hda_intel
 Kernel modules: snd_hda_intel

 Subsystem: ASUSTeK Computer Inc. 8 Series/C220 Series Chipset High Definition Audio Controller

When I select 2.1 sound the subwoofer does not work
