To Reproduce

1. Boot up wiht HDMI external port connected.
2. Run test-case in sof-test with "./multiple-pipeline-playback.sh -c 4 -l 200 -r -t /lib/firmware/intel/sof-tplg/sof-tgl-max98373-rt5682.tplg"

Script:
https://github.com/thesofproject/sof-test/blob/master/test-case/multiple-pipeline-playback.sh

Reproduced rate
Will reproduce the issue within 10 iterations each round.

I wonder if test is opening the wrong PCM as part of the test (or Pulseaudio running on background)? This error trace is expected if trying to play to a HDMI/DP PCM that is not connected to a monitor. This should not happen in normal usage as Pulseaudio/CRAS only show HDMI/DP PCM devices that are connected.
