In case of no audio after updates....

This more of an FYI post because I couldn’t find an answer to it in this forum. I’m running 1.55 and after running rpi-update, I wasn’t showing any alsa devices. I would see something like “Nothing Selected” under Playback–>Audio Output.

After some searching, I found that once I added dtparam=audio=on to /boot/config.txt, after rebooting the audio started to work again.

Hopefully this helps someone else.
