What's the output of the aplay -l and aplay -L commands ? What settings do you have for Audio in EmulationStation's menu (device/card) ?

Also, please add some info about your setup, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.

@clyde said in Failed to find mixer elements error after latest system update/upgrade. Kernel bumped to 4.19.118:

@colosso25 Did you encounter any random "stops" for 1-2 seconds of the system? Because that's what me and some others experienced using the headphone jack. The only solution that we found was to use HDMI sound.

No, not that I know of. I haven't been testing stuff out at that time. I was looking for a solution to this problem.
