Error when running sudo journalctl -p 3 -xb

Hello everyone. I’m a noob here, sorry in advance if this question is not the right subject as Kernel related.
When I run sudo journalctl -p 3 -xb I get this error:
apr 21 22:00:22 myPC kernel: snd_hda_codec_hdmi hdaudioC0D2: Monitor plugged-in, Failed to power up codec ret=[-13]
I don’t have any issues using the pc, so no noticable thing to happen. I run the command simply out of curiosity. Is this something critical and should be adressed? If yes, please let me know what should I do.
I searched for this error in Google but looks like an unsolved topic on the Arch Forum.
Thanks a lot for your answers.
