Configuration problem. Video decode is orders of magnitude more
difficult than audio decode.
Did you follow the recommendations on the wiki page?

I was pretty sure this was not normal but I really have no clue how to fix it.
Linux audio and I have never been very friendly. The wiki only stated to
use another audio driver. I tried installing and uninstalling the pulse audio
driver but it did not appear to make any difference but I was not able
to pick pulse audio as my output device so I am sure I did something wrong.
Do you have any suggestions on further reading?
Thanks
