Intel TGL HDMI/DP codec provides 9 pins (Linux kernel, 9a11ba7388f16: ALSA: hda: hdmi - add Tigerlake support), and with the DP MST enabled, the linux kernel will build 11 output devices (3, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16), and current alsa-lib only maps the first 8 output devices, if users plug the HDMI/DP monitor to the last 3 ports, the users will not see the output device from pulseaudio or gnome. We have experienced this issue on a dell TGL machine with a dock, we plugged 2 HDMP/DP monitors on the dock, but we could only see 1 HDMI/DP output device from pulseaudio or gnome, through investigation, we found one monitor is plugged in the 2nd port from last.
