League of Legends - No sound in Ubuntu Wine Fix

When I first installed League of Legends on Ubuntu with PlayOnLinux (with wine 1.7), there was sound in the game lobby, but none ingame.

What didn't work
First, I tried disabling mmdevapi.dll. That made things worse by disabling all sound, so I re-enabled it.
Then I tried restarting pulseaudio,
killall pulseaudio
pulseaudio -k
Nothing happened.

What worked
Lastly I installed an audio package which was missing on my machine,
sudo apt-get install libasound2-plugins:i386

BAM! It worked! The audio is fixed in-game as well as in the lobby.
