Looks like the audio DSP might not be correctly initialized?

Right now, I'm thinking I might (??) need the code in sound/soc/qcom/lpass-cpu.c to be called.
$ git grep asoc_qcom_lpass_cpu_platform_probe sound/soc/qcom/lpass-apq8016.c: .probe = asoc_qcom_lpass_cpu_platform_probe, sound/soc/qcom/lpass-cpu.c:int asoc_qcom_lpass_cpu_platform_probe(struct platform_device *pdev) sound/soc/qcom/lpass-cpu.c:EXPORT_SYMBOL_GPL(asoc_qcom_lpass_cpu_platform_probe); sound/soc/qcom/lpass-ipq806x.c: .probe = asoc_qcom_lpass_cpu_platform_probe, sound/soc/qcom/lpass-msm8998.c: .probe = asoc_qcom_lpass_cpu_platform_probe, sound/soc/qcom/lpass-sc7180.c: .probe = asoc_qcom_lpass_cpu_platform_probe, sound/soc/qcom/lpass-sc7280.c: .probe = asoc_qcom_lpass_cpu_platform_probe, sound/soc/qcom/lpass.h:int asoc_qcom_lpass_cpu_platform_probe(struct platform_device *pdev);

Is there an equivalent HW block for msm8998?
Vendor kernel has no hits for hdmiif.
I don't see anything relevant downstream :(
Do I need to look at the HW block at address 0xee000000 ?
lpass-lpaif could be LPASS_LPA_IF_REG_BASE at LPASS_BASE + 0x00100000 ?
