[LNL] multiple cases failing to HDMI playback on SDW configurations with gpu_bind disabled

[kv2019i]

Some interaction with recently merged kernel and FW PRs has caused a high rate failure to occur in PR testing:
https://sof-ci.01.org/sofpr/PR9116/build6350/devicetest/index.html

2024-07-08 13:40:30 UTC [REMOTE_INFO] ===== Testing: (Round: 1/1) (PCM: HDMI1 [hw:0,5]) (Loop: 1/1) =====
2024-07-08 13:40:30 UTC [REMOTE_COMMAND] aplay   -Dhw:0,5 -r 48000 -c 2 -f S16_LE -d 10 /dev/zero -v -q
aplay: set_params:1416: Unable to install hw params:

The gpu_bind should be disabled in sof-dev kernel, so not sure why HDMI playback is attempted.

Related PRs merged recently:

• topology2: enable HDMI for all SoundWire production topologies sof#9267 (HDMI tplgs changed)
• AMD SOF based generic SoundWire machine driver  #5068 (it's the sof_sdw mach driver that is used in failing cases)

As this is seen in PR testing marking as P1.

Observed in today's daily run https://sof-ci.ostc.intel.com/#/result/planresultdetail/43591?model=LNLM_SDW_AIOC&testcase=check-playback-all-formats on jf-lnlm-rvp-sdw-1

Other LNL configurations are indeed not affected.

Could this be caused by some device-specific configuration? It did not happen on ba-lnlm-rvp-sdw-01 in the July 7th (planresultdetail/43565) and July 9th (planresultdetail/43642) daily tests. Also not in https://sof-ci.01.org/softestpr/PR1218/build625/devicetest/index.html

EDIT: failed on
ba-lnlm-rvp-sdw-03 in https://sof-ci.01.org/sofpr/PR9276/build6355/devicetest/index.html

This issue still reproducible on latest. Currntly we have WA "NO_HDMI_MODE=true" is set on device enviroment so we are not seeing issue in CI results.

I'll take a look at this, but FYI to @ujfalusi and @ranj063 in case we need to switch.

[ujfalusi]

Only affecting LNL, TGL/MTL HDMI is working fine?

[ssavati]

@ujfalusi this is not observed on MTL. I will check on TGL and update
