AFAIK sound via HDMI on a Pi3 with OpenSUSE aarch64 is not possible (as per release announcement). I am uncertain the status of sound via the analogue jack - has anyone got this working? Certainly on my setup there is nothing after boot in dmesg that looks like a sound driver despite having dtparam=audio=on in my config.txt (which in Raspbian loads snd_bcm2835). And firing Sound module in YaST throws an error “No card found”.
If I can get sound the next challenge would be to install mplayer but it seems to me there are no aarch64 packages in Packman - are these located elsewhere?
I haven’t tried to keep up with all the architectural changes over the years relating to sound…
A better starting point than looking at specific file locations is to open up YaST, verify a sound device is recognized and note its configuration.
~> sudo modprobe snd-bcm2835
modprobe: FATAL: Module snd-bcm2835 not found.
Seems there is no snd-bcm2835 in the build: indeed a filesearch finds no such file whereas in Raspbian it is in /lib/modules/…/kernel/sound/arm/. I guess it either hasn’t been built yet for aarch64 or there is a packaging error. I did try copy the (arm7) version from Raspbian into /lib/modules/4.4.49-16-default/kernel/sound/arm/ but got the same ‘module not found’ error so I guess installing it takes more than just copying a file! Apart from which don’t really expect a arm7 driver to work under aarch64 but it was a clutch at a straw.
