[BUG][CAVS reference firmware] multiple-pause-resume.sh failed in nocodec mode, input/output error

[fredoh9]

Describe the bug Clearly this is CAVS/IPC4 related issue. But I'd like to start a thread from here first. Found aplay input/output error while testing multiple-pause-resume.sh on TGLU_RVP_NOCODEC.

To Reproduce TPLG=/lib/firmware/intel/avs-tplg/cavs-tgl-nocodec.tplg MODEL=TGLU_RVP_NOCODEC_IPC4 ~/sof-test/test-case/multiple-pause-resume.sh -r 50

Even with less iteration, I'm able to reproduce this. TPLG=/lib/firmware/intel/avs-tplg/cavs-tgl-nocodec.tplg MODEL=TGLU_RVP_NOCODEC_IPC4 ~/sof-test/test-case/multiple-pause-resume.sh -r 5

Reproduction Rate 90%, pretty easy to reproduce but not 100%

Expected behavior multiple-pause-resume.sh test return success

Impact multiple-pause-resume.sh test fails

@XiaoyunWu6666 which FW are you reporting here ?

Kernel: https://github.com/thesofproject/linux/commit/4542828f16f1830bbc7dc03ea71e9eba67336708 SOF: 87caf973ebac, fw is CAVS FW, tgl/dsp_basefw.bin

If this bug does not reproduce with SOF FW then we can close.
