But yes, it`s a serious tool which can help you with troubleshooting if you experience lags, pops, crackles whatever.

I`m glad to hear that. Maybe it would be interesting to know what values ppl can get on their system, we could do a small list in here or something (if somebody is interested in this) just to compare how the own system performes to others with a similiar configuration.

This is a very useful tool. I used it as well for my sound problems.

Just to add on.

To find out who is reponsible for dropouts you can use the above programs to monitor your DPC latency while recording/playback. Then you can go to System/Device Drivers (in Windows) and disable the driver that is causing the DPC spikes while monitoring the DPC latency. You want to be careful though, as you dont want to disable essential drivers. The usual culprits are:

-Wireless LAN - this is probably the main offender in laptops
-You might want to disable the "1394 Net" Driver too
-Ethernet Adapter/s (no more internet)
-Modem (who uses a modem these days??)
-PCMCIA controller (on laptops - if not being used)
-Internal Audio Controller (the one that came with the computer), usually "Realtek", "AC'97", etc. These tend to be very resource hungry, and you have a nice interface anyway.
-Unused IDE controllers: in laptops "Secandary IDE Channel" is usually not used (check in properties)

Basically anything that is non-essential can be disabled, but it is usually the ONE device/driver that is causing the issue. Give RATT a try, it's very useful. It might be advisable to disable some of these devices in the BIOS too (if you know what your doing). Finally, if nothing works, it might be time to upgrade your computer
