Re: [Discuss-gnuradio] Audio woes

[Marcus Müller]

Hi Marcus,

I do agree on the "Linux audio is fragmented, and neither PA nor ALSA are consistent in documentation and configuration, and that's seriously irritating" aspect.

So, first of all, I always try to circumvent Pulse. Try sysdefault as audio device name (that's the physical device that pulse uses, on FC21/22; I think it was on FC20, already). `aplay -L` might tell you things I can't ;)

Other than that: might be systematic[1]. Did I mention I really like[2] how Ubuntu doesn't try to bring people to discuss problems with the upstream developers?

Best regards,
Marcus

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"].
