I have a 4G Rev 2 Rock64 that is running like a champ on current - 5.4.2 as of this writing, as far as USB and Ethernet are concerned. I did have to blacklist UAS for all my USB drives, and now the board is rock solid even with heavy disk and network IO.

 

I do have one problem though, I have no sound.  I have the following loaded (automatically):

root@chdock:/home/sugata# cat /proc/modules |grep snd
snd_soc_rk3328 16384 0 - Live 0xffff800008dc9000

And yet, I get this:

 

root@chdock:/home/sugata# aplay -l
aplay: device_list:272: no soundcards found...

I searched around this forum and nothing obvious came up. Any ideas?

Any ideas?

- driver not ported?

- driver exits but there are no definitions in the device tree (for this board)?

 

It is expected that features doesn't work in bleeding edge kernels. There is no rush.
