Looks like the audio DSP might not be correctly initialized?

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 ?
I haven't dug into audio. Not entirely sure how to help here.
0xee000000 is DDR on 8998.
LPASS is at 0x17000000
lpass-lpaif could be LPASS_LPA_IF_REG_BASE at LPASS_BASE + 0x00100000 ?
Regards
