[BUG] PCM IO error with multi stream capture topology on pause-resume test

[bardliao]

Describe the bug
PCM IO error happen when I run the "~/sof-test/test-case/multiple-pause-resume.sh -r 50" test.

To Reproduce

1. export TPLG=/lib/firmware/intel/avs-tplg/sof-tgl-nocodec.tplg
2. ~/sof-test/test-case/multiple-pause-resume.sh -r 50

Reproduction Rate
100%. But I can't reproduce this issue if I start two PCMs and pause-resume them manually.

Expected behavior
PASS "~/sof-test/test-case/multiple-pause-resume.sh -r 50" test

Impact
This is a blocker to add multi capture stream on topology.

Environment

1. Branch name and commit hash of the 2 repositories: sof (firmware/topology) and linux (kernel driver).
   • Kernel: topic/sof-dev: ec7f152
   • SOF: main: thesofproject/sof@1e3a4cf + topology2: add ssp multi stream capture  sof#6601
2. Name of the topology file
   • Topology: cavs-tgl-nocodec.tplg
3. Name of the platform(s) on which the bug is observed.
   • Platform: {TGL}

Screenshots or console output
I can't find useful information from kernel or firmware log. Below is the console output.
