<DIV><FONT size=2 face=Tahoma>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'.</FONT></DIV>
<DIV><FONT size=2 face=Tahoma></FONT> </DIV>
<DIV><FONT size=2 face=Tahoma>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.</FONT></DIV>

<DIV><BR></DIV>Hi,<BR><BR>I wonder if anyone has had problems with audio
crackling? <BR>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.<BR>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. <BR><BR>System
info: <BR><BR>Airmate out into Soundcard in (channels 1 & 2)<BR>mAirlist
(6 Channels) and computer audio (2 channels) via Soundcard outs into Airmate
channels<BR>Asus P5K-VM motherboard with an Intel Core2 duo CPU. (it's a Red
Sub computer with a few extra things I've added) <BR clear=all>The CPU
cooler is a bog standard one but with a funnel that directs the hot air out of
a vent on the side. <BR><BR>Anyway, if you have an idea, I'd really appreciate
any advice. <BR><BR><BR>Peter Vautier<BR>London Chinese Radio<BR>-- <BR><FONT
