 HDA-Intel: present up to 8 HDMI/DP outputs via "hdmi" device


Is there any reason for you to disable on-board hda controller and alc888

strange that only two ports are available

Active Profile: output:hdmi-surround-extra0
    Ports:
        hdmi-output-0: HDMI / DisplayPort (priority: 5900, latency offset:
0 usec, available)
            Properties:
                device.icon_name = "video-display"
            Part of profile(s): output:hdmi-surround-extra0
        hdmi-output-3: HDMI / DisplayPort 4 (priority: 5600, latency
offset: 0 usec, available)
            Properties:
                device.icon_name = "video-display"
            Part of profile(s): output:hdmi-surround-extra3

is these emulated ELD since monitor name, manufacture id, product id are
absent ?
