[Sound-open-firmware] HDMI audio not working on Up^2
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?
Thanks Guennadi

No, your cable and monitor should be fine. I think this regression has been added to the GH issue tracker. Can you check.
Thanks

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

You need to set the PortN-PinM mixers, otherwise the hw_params will fail. It's super painful and I don't know why it's needed but that's what it is for now. I typically look for the dmesg, find out which port is not disconnected, and usually set Port6Pin0 to 1, then use hw:0,1 to get things to play. I don't have the hardware with me so can't provide better advice. Also please use the dapm graph tool to make use everything is setup correctly.

Guennadi, could you document this on sof-docs with a paragraph and your example config / changes. Nothing long needed, just enough to point others in the correct direction.
Thanks

Guennadi,
here're my pin/port settings: Pin5-Port0/1/2 to cvt2 Pin6-Port0/1/2 to cvt3 Pin7-Port0/1/2 to cvt4
And as Liam mentioned SOF master has a regression that still causes a failure. But you could try the cml-003-drop-stable branch for now and it should work.
Thanks, Ranjani

Usually, I set all pin and ports to the same cvt eg cvt2. So I can open the same device eg -Dhw:0,2 no matter what pin/port does the HDMI actually connect to.

Guennadi,
here're my pin/port settings: Pin5-Port0/1/2 to cvt2 Pin6-Port0/1/2 to cvt3 Pin7-Port0/1/2 to cvt4
Actually the PinX-PortX is something need to be set within the hdmi-codec. The codec need some route setting. The Pin6-Port0 will be default one if you are using HDMI connection. If you are using DP or other port, change the Pin accordingly. Now take HMDI with Pin6 as example:
If you would like to test with HDMI 1/2/3. Please set Pin6-Port0 to cvt2/cvt3/cvt3 and test one by one. (1 => cvt2, 2 => cvt3, 3=>cvt4)
If you would like to use MST-HUB, you need to set Pin6-Port0/1/2 to cvt2/cvt3/cvt3. Then you can play each on each monitor with different HDMI PCM FE.
Thanks Xiuli

Hi,
Thanks for all the replies so far, however I'm still unable to play audio on HDMI. As suuggested by Ranjani I checked out the cml-003-drop-stable branch and I'm still getting the same errors. As a mixer configuration I tried mapping all pin5 ports to cvt2, etc. - also as originally suggested by Ranjani. That should work, right? I tried all 3 alsa devices (hw:0,[123]) and I'm getting the same error. Is the actual meaning of all the pins, ports and cvts on Up^2 documented anywhere?
Thanks Guennadi

Hi Guennadi,
Just to confirm, you're using the fw and tplg from the same branch?
Thanks, Ranjani
