Hello,
My Pine64 has served my daughter well for her online courses during the pandemic, loaded with Armbian. As someone more into Fedora, I'm always looking for opportunity to switch on this cheap SBC.
It hasn't been successful until Fedora 35 XFCE AArch64. With the help of arm-image-installer, the recent AArch64 booted and runs quite well, with one exception: no Sound from HDMI port.
There's audio from 3.5mm jack thus I'm pretty sure the player, codec and sound server are all right.
I tried to poke around the XFCE sound server widget but it seems HDMI wasn't recognized as a device under Fedora 35. Below are output from Fedora running updated kernel 5.14.14:

Despite snd_soc_hdmi_codec being loaded in both systems, the Fedora 35 lacks the sound subdevice sun50ia64hdmi that presents under Armbian.
I had tried searching Pine64 and Armbian forums for clues. But the threads showing up are either several years ago on BSP kernel, or trying to get sound from 3.5mm jack port.
Much appreciated if someone here can point me in the right direction to further diagnose or solve this problem.
Kind regards,
Tommy
