Hello,
Recently I found that audio stopped working on my Banana. Last time (3 months ago) I was using shairport to stream audio over LAN and all was working just fine. 
Now I see that somehow information about audio card was removed:

root@bananapi:~# alsamixer
cannot open mixer: No such file or directory

root@bananapi:~# cat /etc/asound.conf
cat: /etc/asound.conf: No such file or directory

I already try apt-get update && apt-get upgrade && apt-get dist-upgrade. My system information:

Up...

Try this. Switch to beta, update and enable audio codec (armbian-config -> system -> hardware configuration)

Note that switching to beta repository might break the system - its untested area.

Switching to beta was successfull, but during entering 'hardware configuration' I get errors from grep (Try 'grep --help' for more information) and afer that window with enable/disable is empty (see atachement).  Any idea why this happens?

Probably some armbian-config dependencies must be missing but IIRC you need to start with a new image because overlays need also new boot script. We plan to rebuild images for A10/A20 next week. There this should work and if not, we will try to resolve the problem. Wait.

It shouldn't be related to overlays - BPi has analog sound enabled for almost 2 years. What strange is that /boot lists kernel 4.11, uname -r lists kernel 4.9 and lsmod output is too empty - there should be a lot more modules loaded. It could be the result of a broken SATA/USB installation or apt upgrade.
