Several in fact. :( (1) I get a random, single crack from one channel of the card, only while in SONAR X1 Prod. It's about every 10-30 seconds apart. (2) When I turn off the PC, I get a resonant, tuneful flatulent sound from the speakers. It lasts about 5-6 seconds. Both of these problems have occurred with two different 2496 cards. (3) I have tried to instal the latest driver and it says I have a side by side error and will not run. I have tried moving the card to another slot, reinstalling it, changing latencies for the SONAR cracking problem and contacting M-Audio support. So far none of these has worked. So if anyone has any ideas about any of the problems, I would really appreciate any help.

i had a 2496 card, before i got my audiophile 192 card, never experienced any issues at all.

if the same thing happened with two different cards, then i'd say the problem is in your pc setup.

sound like a clocking problem, or, something in your pc's OS is stepping on the card signal.

...or maybe the PCI bus.

Thanks for the replies. Trouble is I have tried different slots, and the problem only occurs in SONAR, and only in one channel.

My Delta 44 crapped out exactly like you're describing.  pops and crackles.  Mine started in one INPUT only and then it was on ALL inputs.

I threw the card away since it wasn't worth repairing.  mine was only about 4 years old.

Well mine is only 4 _weeks_ old! I am guessing it's a driver issue, or some incompatibility with SONAR, because two different cards in different slots have done the same thing.

OK. Here is what is happening now.(1) The crackle / pop is still there after loading the latest driver from m-Audio (2) It happens ONLY in one channel (3) It happens ONLY when SONAR X1 is running (4) It happens ONLY when there is a project loaded, even if the project is empty, without any tracks at all. (5) It happens exactly the same whether I am plying or the project is just sitting (6)It has stayed there through all upgrades of X1, from original download to loading up Expanded X1e. I have tried buffers, different sample rates, trying to match SONAR's settings to the card's, profiling the card, several times....

do you have previous versions of sonar?  does it happen in 8.5 or below?

which operating system?  I had problems like this due to shared interrupts with the video card on WinXP, but I dont think I've had to even check things like that in Win7.

Thanks for the reply. This is driving me nuts. Luckily so far it has not affected my actual output, but it is extremely irritating. I have a copy of Sonar 8.5, but not installed. I will give it a go. Thanks I have Win 7 64 Home Prem SP1. I will check for conflicts anyway.

OK. I have installed SONAR 7 Prod and loaded up a song. I have sat (sitten??) here for 5 minutes doing stuff on another PC and it has been as silent as the grave. I have deliberately turned the latency down as far as it will go (5.8ms, 2 buffers). I have tried ASIO , which is what my X1 is set to, and still no clicks. CLUE...I do get one click as I open a project. It is the same click that I get in X1 all the time. One channel, lots of HF/supersonics, I think. I base that last on the fact that it is barely audible, but the meters give a huge jump in the card's mixing programme. I have very good high hearing and can gear "supersonic" (25KHz)alarms in shops sometimes. Not boasting. It's a PITA. But it means if I can hardly hear that spike, it's very high. (Or very fast I guess)

NEXT! (1) If I open X1, then open a project, it clicks as I open the the project, then keeps clicking as long as the project is open. (2) If I then open SONAR 7 and open a file, I get a single click as I open a project, then silence. (3) If I then _close_ SONAR 7, reopen and then load a project, there is NO CLICK. (4) But if I then close SONAR 7, and open SONAR X1, the open a project, it clicks as the project loads, and keeps clicking. NOW. (5) If I then close sonar x1 and reopen SONAR 7 and load a project, I GET THE CLICK AS I OPEN A PROJECT.....See (1)....X1 is doing _something_

then it's probably time to call support CW support on this one.  good luck!

OK. I got onto to support and they suggested a few things like disabling all startup applications (boy! I thought I was getting the PC nice and mean and clean already) and also playing with buffer settings. But what did the trick was resetting the Config file to defaults. Not sure what that has done exactly, but I seem to have some latency there although it's supposed to be 5.8mS. I can actually hear the time between activating a note and its playing. I doubt I could hear 5.8mS and it seems worse than it was before.

so, it wasn't the card, but the system.

http://www.thesycon.de/deu/latency_check.shtml Have you used such a program to check your computer??

Late to the Party and IE10 someone can have: http://soundcloud.com/spa...songthatneverwas-remix ?????

@batsbrew "so, it wasn't the card, but the system. " No not the system as such, but how SONAR was set up and interacting with the card. I can't say more (because then I have to kill you :D) because I fixed it by resetting all the Config file settings to default and have no idea what setting did it. Part of the try to fix involved the system, but made no difference to either the SONAR click or the system "plangent bellow" at shut down.

@spacealf "http://www.thesycon.de/deu/latency_check.shtml Have you used such a program to check your computer?? " No, but I will have a good look at it. Thanks

Actually it's interesting, because there seems to be worse latency when I first activate a note on a given instrument, having opened PRV on that instrument, then it's a lot shorter for all subsequent activations. . I am using PRV here, so it's not any sort of external latency.

HAH! Things are getting circular! I HAD run that latency app and it says I have 500uS of latency! So should not be too much trouble there.
