  • Audio over HDMI Tonga and AMDGPU


    I just spend hours trying to get this to work and I just couldn't find any decent Info on the net if HDMI audio is working with Tonga GPUs and the open source driver.
    I am on arch with the latest mainline kernel and fglrx is just no option, since downgrading X would be necessary.
    Alsamixer detects this device:
    Card: HDA ATI HDMI
    Chip: ATI R6xx HDM

    And pulse shows the correct device name and R9 285/380.
    Aplay on all devices will not output any audio.

    I do not expect you to troubleshoot my problem for me, but I hope some of you have info if it is even working in general. Because if not
    I can finally rest and play the waiting game.
    Also crimson for X18 when?

    Thx for any input.

    You need to use DAL for audio on amdgpu.

      What would be the best way to do this at the current time?

        Either grab the patches from the dri-devel mailing list or use my drm-next-4.6-wip-dal branch.
