I am trying to install ArchLinux on my Jetson TK1, I have manage run v5.8.1 mainline and get working, my pcie WIFI/BT card, Ethernet and other stuff but I still having some trouble to configure the HDMI audio on my jetson-tk1.
I have added “load-module module-alsa-sink device=hw:0,3” to my /etc/pulse/default.pa and I can see a sink entry in the “pactl list” output. In the graphical interface, at the sound preferences output, there are two entries called Built-in Audio and Built-in Audio Stereo.
Also if I run “aplay -l” I can see the tegra-hda device, however, no audio comes out from the HDMI to my TV. One weird thing is that tegra-hda sound is not recognized as a card by pactl but only as a sink, I really not sure if this is the expected behavior.
I really don’t know what to do about this…
PS: I have publish a script to install ALARM in the Jetson TK1 at my github repo https://github.com/LordRafa/ALARMOnTegraK1
