No audio devices found after update

[bwestover]

I recently updated to v.3.3.0 on a RPI 3. After this update I don't have any sound.

Apologies for the double post (I also logged this on the community forum: http://world.kano.me/forum/topic/upgraded-to-3.3.0-now-audio-devices-are-not-found). I'm not sure if that location is monitored and I figured you would want to know about this asap. 🙇

I have done a bit of troubleshooting:

It seems ALSA can't see the device:

$ sudo aplay -l
aplay: device_list:268: no soundcards found...

Let me know if any additional information would be helpful

Hi @bwestover , sorry about this.
On the pi3, there is supposed to be an entry in the config file /boot/config.txt which enables the audio device. Could you post your config.txt? It is on the SD card as just 'config.txt' if you plug it into a pc.
It should contain the line dtparam=audio=on at some point.
If this is missing we would like to know how this happened, so it would be useful also to post any logs you might have from the update. These can be printed by kano-logs show -l kano-updater
Thank you.

@Ealdwulf that parameters was indeed missing. Adding it and rebooting fixes the sound 🎉

I'm afraid the output from that log command doesn't look to have much:

Thanks! I'll let the customer support team know the solution in case it affected anyone else.
