[cma-l] Audio crackling

[Two Lochs Radio]

Does the crackle stop for a while if you stop and restart the audio stream? If so, that would suggest a small bite rate mismatch is not being properly handled and is resulting in repeated buffer overflows, which depending on how well the software handles dumping the excess data can sound like a crackle or a 'glitch'.

But the description 'crackle' can cover a multitude of effects. is it possible for you to post a little audio sample of it somewhere we can access (or email me a small pice directly if you want) in case the actual sound triggers any other thoughts.

  Hi,

  I wonder if anyone has had problems with audio crackling? 
  I have recently changed to a different streaming PC, (because it was XP, and I had a Marian marc8 midi sound card which has 8 ins and outs, but doesn't support Win7), and it was fine for about a month, until it started crackling. I put all the audio on a seperate HD, and because they are quite close together, I also fitted a large fan next to them, which delivers quite an icy blast across the disks.
  It starts crackling after a few hours, and it ruins the stream. It is solvable by rebooting. I originally thought it could be something overheating, but since it is solved by rebooting, without the time for anything to cool down, I don't think that is it. 

  System info: 

  Airmate out into Soundcard in (channels 1 & 2)
  mAirlist (6 Channels) and computer audio (2 channels) via Soundcard outs into Airmate channels
  Asus P5K-VM motherboard with an Intel Core2 duo CPU. (it's a Red Sub computer with a few extra things I've added)  
  The CPU cooler is a bog standard one but with a funnel that directs the hot air out of a vent on the side. 

  Anyway, if you have an idea, I'd really appreciate any advice.
