Nope, these are all driver issues or maybe hardware issues.
ODJOL : If you’ve upgraded from Vista (or fresh installed from XP), then you need to install the relevant W7 Specific audio drivers for your device. Go either to your PC/Laptop manufacturer’s website to look for W7 specific drivers. If they don’t support W7 for your particulat unit, one possible way to “solve” this issue is to try and install Vista drivers in compatibility mode. However, be advised, this does not work systematically on every machine. Failing that try the chipset manufacturer (Realtek, VIA etc)
Sirboxalot : W7 wasn’t released in 2008, so no point in trying those drivers. Same goes however, check the Asus site for W7 drivers. If non, try Visat, as above.
Crackling can also be caused by faulty connections, interference from WiFi/wireless connections, interference from a HD, if a sound card then it may be too close to the video card (in the case of a PC) and many other reasons.
Latency spikes can be identified using DPC, and most are due to Hardware Services cutting in and out, the most frequent being WiFi or wireless connections. Simply turn off those services governing your Hardware one by one until the spikes go away, then you’ve found your culprit. Be careful when doing this though !
If your sound device is sharing an IRQ, and if you have a PC, reseat the device in another PCI socket
psikofunkster : Your PC/Laptop maker is responsable for providing the correct audio drivers and if they decide not to support W7 for a particular one of their products, then thats their fault, not MS. W7 uses different types of drivers than XP or Vista.
Neurot5 : no, the common denominater normally is upgrades without finding W7 specific audio drivers.
