[Discuss-gnuradio] Audio woes

[Marcus D. Leech]

I have a Xeon server system with a SB X-Fi USB sound module on it. 
Changed configuration so that system sounds play on it, etc.

Youtube works just fine.

But any GR app that tries to use it gets *massive* underruns, regardless 
of the sample rate I use--I've tried 48K, 32K, 8K, 44.1K, 96K.  The pulse
  audio daemon appears to be configured for 44.1K as its natural rate.  
And as I said, system sounds and Firefox have no problem with audio
  output at all.

This is F20.  What do I need to know?  [As an aside, I hate Linux 
audio.  It's the most fragmented and frustrating piece of Linux, and I'm 
a total
  Linux fanboy, but I hate sound configuration, and the "brand-new 
sound architecture of the week"].
