===== Known issue =====
  * In portrait mode, 720x1280 DPI works on 1080x1920 resolution. http://forum.odroid.com/viewtopic.php?f=137&t=21785

  * Audio passthrough for both AC3 and DTS sources where every few seconds there's an audio dropout.
   Workaround: Write the codec value to //**/sys/class/audiodsp/digital_codec**// sysfs file before executing the media player.
    
**AC3**
<code>
$ echo 2 > /sys/class/audiodsp/digital_codec
</code>
**DTS**
<code>
$ echo 3 > /sys/class/audiodsp/digital_codec
</code>

If there is //no sound// or //frequent sound drop// when using HDMI passthrough, then please reboot the system.
