Comment 5 for bug 1959030

Apologies in advance if I don't use the right syntax or formatting here; I'm pretty new to Linux and this bug reporting process. I believe I am seeing the same symptoms running 5.15.0-41-generic #44-Ubuntu SMP Wed Jun 22 14:20:53 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux on Lubuntu 22.04. The sound card seems to be recognized:

$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Audio [Intel HDMI/DP LPE Audio], device 0: HdmiLpeAudio [Intel HDMI/DP LPE Audi]
  Subdevices: 1/1

I used to get sound when I ran
$ speaker-test -D plughw:CARD=rt5651,DEV=0
but not anymore.

pavucontrol-qt only shows a Dummy output.
