Describe the bug
The WoV tplg has below connections:

    DMIC ------> KPB ------------------------------> host_copier
                          |                                  ^
                          |                                  |
                          |----> micsel ----> dummywov ----> virtual_widget

ppl0 contains DMIC, KPB
ppl1 contains micsel, dummywov
ppl2 contains host_copier

The driver triggers multiple pipelines with a single IPC with SOF_IPC4_GLB_PIPE_STATE_EXT_MULTI set in the ipc message extension field. The IPC message is:
ipc tx : 0x13000004|0x1
payload : 0x00000003 0x00000002 0x00000001 0x00000000
This sequence doesn't work and the trigger to running state will fail.

However, if we trigger single pipeline in sequence like:
ipc tx : 0x13000004|0x0
ipc tx : 0x13010004|0x0
ipc tx : 0x13020004|0x0
This sequence works.

ps: this bug is related to the trigger sequence.
I tried to send ipc message:
ipc tx : 0x13000004|0x1
payload : 0x00000003 0x00000000 0x00000001 0x00000002
It works.

Use a pipeline, which contains a KPB component, to record. For example, on MTL nocodec platform, run:

arecord -Dhw:0,11 -c2 -r16000 -fs32_le -M -N 2.wav -vvv

Reproduction Rate
100%

Expected behavior
Record works well.

Impact
The pipelines which contains kpb won't work

ps: The dmesg shows error at deleting pipeline, but the mtrace shows error before this point. mtrace shows error at trigger multiple pipelines to running state.
