Hi Liam,
I see some issues both in SOF and the kernel, e.g. https://github.com/thesofproject/sof/issues/1114 and https://github.com/thesofproject/linux/issues/737 but they seem to be differeent and in fact e.g. the latter is "positive" for me - since it's reporting a problem with PM, it implies, that without entering low-power states, HDMI audio was working.
Thanks Guennadi

Hi,
I tried to test HDMI audio on Up^2 and hdac_hdmi_set_hw_params() is failing with -ENODEV because no port is assigned. Some very light analysis and debugging showed, that hdac_hdmi_pcm_open() hasn't been called, but it might wrong. Are there any non-trivial requirements to use HDMI audio on Up^2? Can it be, that my monitor or my cable aren't good enough?
No, your cable and monitor should be fine. I think this regression has been added to the GH issue tracker. Can you check.
Thanks
Liam
