Windows 7: Cracking/intermittent audio and lag.

30 Jan 2011   #1

Windows 7 Ultimate.
Cracking/intermittent audio and lag.

Hi all,

I'm having a bit of an issue which I can't seem to solve.

Yesterday I noticed that when playing audio on my PC (whether on a video, MP3, DVD, playing a game) my PC will lag noticeably and the audio will crack/drop out. This only seems to happen while I am actually active on the PC (MP3/video playing in the background while browsing the internet, for example). The issue does not occur with line in audio (I have Foxtel audio coming into the card).

I have tried the following:

- Updated audio drivers
- Different sound card (Audigy 2 ZS primarily using onboard sound)
- Reinstallation of Windows (Windows 7 Ultimate)
- Reflashing BIOS with current version
- Disabling devices which I don't need as specified by DCP Latency Checker (WiFi adapter, firewire adapter, etc)

My current hardware:

- Intel E8400
- Asus P5K-E
- 4GB Kingston RAM (not sure of the exact details, but can find them if needed they're 4x1GB)
- nVidia GTX 275

DCP Latency Checker tells me the following:

Some device drivers on this machine behave bad and will probably cause drop-outs in real-time audio and/or video streams. To isolate the misbehaving driver use Device Manager and disable/re-enable various devices, one at a time. Try network and W-LAN adapters, modems, internal sound devices, USB host controllers, etc.
I've had a look at other threads on this forum and others - unfortunately none of the solutions specified on this forums work for me.

Does anyone have any ideas as to what I can do to solve this?
