This is on my banana pi pro. Since I installed the system, I've never had any issues with any updates.
I had sound prior to applying last updates, as there were so many updates, not sure what to check. There's no /proc/asound.
I'm following up on one of my rpi3 to see what happens there.
attached alsamixer-sun4i-codec.jpg was from 11/19/20.
thanks
It's missing from the driver list in menuconfig entirely despite having the dependencies set correctly, so it hasn't been built.
I'll have a look at it for the next kernel update.
Stuart, Thank you!, you've been so spot on with everything, I'll let this one slide .
That's weird - the module is surfaced within the drivers list in Linux 5.10.7 but wasn't there in 5.10.5. I'll push that out in the next update.
Ironically, Phil and I recorded an episode where I tested reinstallation using the new Kernel on the Banana Pi and it worked fine. I didn't test sound though!
What happens when the sun4i-codec is loaded as a module is as follows.
I haven't checked if it works on the Banana Pi yet, but whilst this doesn't seem to cause any runtime operational issues on other platforms, I can't ship a kernel out in this state.
I've removed the sun4i driver again until I have time to look at it.
You may want to revert to the 5.4 Kernel series until then. The last kernel of that series I packaged was 5.4.81. I can upload them if you need them.

Restored Allwinner A10 sound driver for the Banana Pi
I occasionally checked /proc/asound/ since I created this thread, just noticed something there, sound is back on my bpi pro.
