[BUG] DMIC test fails to find non-existing card 0

[harajend]

Describe the bug
"verify-kernel-boot-log" test case failed with error message "amixer: Cannot find the given element from control default"

Triage details
The test script is looking for Sound card 0 by default, but in this case, Sound card 1 is enabled; hence, the test result is FAIL

To Reproduce

1. Launch Terminal in Linux DUT and run below command line
   • "TPLG=/lib/firmware/intel/sof-ipc4-tplg/sof-ptl-rt722-4ch.tplg MODEL=PTLP_RVP_SDW SOF_TEST_INTERVAL=5 ~/sof-test/test-case/verify-kernel-boot-log.sh"

Expected behavior
Test script should pick sound card dynamically

Avoid screenshots when not necessary, use copy/paste:
https://docs.zephyrproject.org/latest/develop/getting_started/index.html#use-copy-paste

This is a good example of when not to use screenshots because neither the title nor the description has relevant keywords (DMIC raw capture switch)

This looks like a real issue; I added a test specifically for this (cc: @kv2019i )
