title: aplay / alsaplayer - sound not working for normal user
body: <p>I cannot use alsa as a normal user (resulting in me not having sound in chromium).</p>
  
  <p>I am guessing it has something to do with permissions. Adding myself to group audio didn't help.</p>
  
  <pre><code>[zarac@towelie ~]$ grep audio /etc/group
  audio:x:92:mpd,zarac
  </code></pre>
  
  <p>Testing sound as normal user:</p>
  
  <pre><code>[zarac@towelie ~]$ aplay /usr/share/sounds/alsa/Noise.wav

  <p>Any clues to what might be causing this is appreciated. Perhaps something needs to be chmodded somwhere?</p>
