Crackling in Ableton

How do,
I have crackling/popping/fuzzy noises in Ableton when using Sylenth1 and other VSTs - More so when it's a big lead sound or a few instances of Sylenth1 together, for example. After I make drums I can't really continue due to this irritating nonsense!
I have 4GB of RAM (2GB is slow RAM that I haven't updated in a while) and an Audiophile 2496 sound card. Is this sufficient? Could there be any other cause? I changed my default warp mode to complex after reading it might help on another forum, although it didn't make any difference. Any other audio settings that could help it?
Any help appreciated

| Hey man, go into your audio settings and try increasing your soundcard's latency a little bit. |

yeah, it definitely sounds like there's a latency issue going on,
so just make sure you haven't selected the wrong audio driver by accident, if not, increase the buffer size.
Running @ 41000 hz I'm down to like 256, heck even 128, and I have no problem running synths like zebra, sylenth1 etc, with massive amounts of both effects and automation. at 48000, i have to increase it, so I have it at 1024 just to be sure everything runs smooth. But I am running a beta version of FL, so perhaps i can lower it with a more stable DAW. I also use Live8 sporadically, but latency issues is probably the one problem I haven't encountered.
For the record, I have the Audiophile 192. So our cards are pretty comparable. And I'm sporting a Core2 Quad clocking in @ 2.5 ghz and 4gb's of RAM. |

just to add the explanation where the crackles are coming from: Live renders audio for the sound card in little chunks of a certain size, the buffers. if you have a very small buffer size set, then it's possible that you get the occasional chunks that take more than 100% CPU - Live can't finish generating the audio before it has to generate the next chunk, and there are miniscule drop-outs: the crackles.
Increasing the buffer size means that you have a greater chance of variety within the chunks in terms of CPU load, so that Live has a better chance to finish the chunk before the next one is due.
The length of the buffer however determines how quickly Live can react to user input (it can't change course in the middle of a chunk), so you want to keep that as low as possible.
How fast it can generate the sound and send it to the card depends on your audio drivers too. With ASIO or WASAPI drivers, you can bear much lower latency than with standard Windows drivers, for example. So if you're not using an ASIO driver yet, that could make a difference. |

| Your CPU is probably bottlenecking as your sound card isn't pulling its weight. |

| Yeah you left out one of the most important details - what CPU are you running? |

| look under preferences, audio, and then output buffer. Play around with that until it gets sounding good. |

Thanks for the answers guys. I am already using ASIO drivers, and my cpu is an AMD quad core 2.8-3GHz - Can't remember the exact speed/model.
I managed to change the latency and buffer size in the ASIO panel via the hardware configuration button in Ableton's audio settings - That's the only way it lets me do it, as under latency in Ableton I can only alter the Driver Error Compensation , which in turn alters the overall latency.
Anyway, it helped a lot and for the most part it sounded perfect, but still when I came to a couple of instances of a VST it still buffers quite a bit. Have I done it right, should I up the buffer/latency more in the ASIO panel?

Why arent you using the M-Audio ASIO drivers? just curious...
you could try going from 512 to 1024 samples - downside is more noticeable latency when using your midi controller etc.. |

| As I suspected. Select the m-audio driver instead of that asio4all piece of . You should notice a huge difference. Asio4all is for people who do not have a ASIO compatible soundcard, and you're not one of those people. |

| I should have mentioned. I have always had the M-Audio ASIO selected in the past, it crackles like mad. Only when I changed to 4all did it start to help. |

| You do have an M-Audio card, right? Just making sure... |
