I have Arch running on a Dell E6530 for a while now, but recently I changed from nvidia to Nouveau drivers, and I cannot get my HDMI audio to work.
Video output is perfect, and all audio outputs on the laptop (3.5mm jack, speakers) work flawlessly; just HDMI audio that is failing. Here are some things I gathered:
$ lspci | grep Audio
00:1b.0 Audio device: Intel Corporation 7 Series/C216 Chipset Family High Definition Audio Controller (rev 04)$ sudo lspci -H1 | grep Audio
00:1b.0 Audio device: Intel Corporation 7 Series/C216 Chipset Family High Definition Audio Controller (rev 04)
01:00.1 Audio device: NVIDIA Corporation GF108 High Definition Audio Controller (rev a1)$ aplay -l
