    @echudy Not an SOF issue, this is a configuration issue, you need to set the controls correctly. Typically this is done by checking which pin is connected, then setting the Pin5/6/7-Port0 Mux to 1 (for HDMI1 path), 2 (for HDMI2 path) and 3 (for HDMI3 path).
    The same requirement applies to the cAVS/SST driver, this is not SOF specific....

    -19 means either you did not connect a HDMI monitor to the device or you have wrong set in alsamixer

    A working hdmi setting is look like above.

    Notice here only port 6 is connection to a monitor so I can see below message in dmesg

    [    3.984807] HDMI HDA Codec ehdaudio0D2: hdac_hdmi_present_sense: disconnect for pin:port 5:0
[    3.985075] HDMI HDA Codec ehdaudio0D2: hdac_hdmi_present_sense: disconnect for pin:port 7:0

    Which means I can only have port6 thus HDMI 2 working.
    So after you have a monitor connected, you need to check the dmesg to determine which card to use.

    Ok, i did this steps:

    • connect monitor with HDMI and restart due to catch dmesg notification. I see the same as you:
    [    5.152543] sof-audio sof-audio: tplg: load pcm HDMI1 3
[    5.152545] sof-audio sof-audio: tplg: load pcm HDMI2 4
[    5.152547] sof-audio sof-audio: tplg: load pcm HDMI3 5
[    5.162688] HDMI HDA Codec ehdaudio0D2: hdac_hdmi_present_sense: disconnect for pin:port 5:0
[    5.163424] HDMI HDA Codec ehdaudio0D2: hdac_hdmi_present_sense: disconnect for pin:port 7:0
[    5.234380] sof-audio sof-audio: creating new PCM HDMI1
[    5.234385] skl_hda_dsp_generic skl_hda_dsp_generic: snd-soc-dummy-dai <-> HDMI1 3 mapping ok
[    5.234392] sof-audio sof-audio: creating new PCM HDMI2
[    5.234397] skl_hda_dsp_generic skl_hda_dsp_generic: snd-soc-dummy-dai <-> HDMI2 4 mapping ok
[    5.234404] sof-audio sof-audio: creating new PCM HDMI3

    • so i set alsamixer to pin 6: cvt3
      image

    • pin6 is HDMI2, so I use command to play:
      aplay -vv -Dhw:0,4 file_sound.wav
      image

    in dmesg I still see code -19:

    [  361.469883] HDMI HDA Codec ehdaudio0D2: ASoC: can't set intel-hdmi-hifi2 hw params: -19
[  361.469894]  iDisp2: ASoC: hw_params BE failed -19
[  361.469899]  HDMI2: ASoC: hw_params BE failed -19

    I remember there is a hdac-hdmi codec driver patch to enable HDMI playback on WHL for sod-dev?
    If that patch is merged now?

    Confirmed with bard, please check if you have 441b4b0
    In you kernel repo.
    I can see from af44aa9 there is no this patch, please cherry-pick it.

    Still the same, HDMI doesn't work.
    Error -19 disappeared.

    After play using HDMI2 (hw0,4) I have only this in dmesg:

    audiodsp@lab201:~$ dmesg
[  414.479628] sof-audio sof-audio: pcm: open stream 4 dir 0

    @emilchudzik please add ccflags-y += -DDEBUG to the Makefiles in sound/soc/sof/ sound/soc/sof/intel sound/soc/codecs sound/soc/intel/boards and submit the full dmesg log as attachment

    @emilchudzik Same branch/commit works on my WHL RVP. But there is only one DP port on my HWL RVP which is pin 5.

    [    3.440683] HDMI HDA Codec ehdaudio0D2: hdac_hdmi_present_sense: disconnect for pin:port 6:0
[    3.440982] HDMI HDA Codec ehdaudio0D2: hdac_hdmi_present_sense: disconnect for pin:port 7:0

    So my command is aplay -Dhw:0,3 48k32bitCalifornia_Dreaming.wav -vv.

    It seems like a monitor issue.

    • IIyama X2472HD:
      available only HDMI and JACK output - screen is visible, but unable to play using aplay

    • Dell U2414Hb:
      available DP and HDMI and JACK output - on both HDMI and DP can play and sound on stereo JACK works.
