I’ve also read that some Method 7 – Try Different Audio Port on PCĪs strange as it may sound, you could have your speakers or headphones plugged into the wrong jack on your computer. Any other type of real-time software should be disabled. This includes real-time anti-virus software (even Security Essentials) or real-time CPU/hardware monitoring software. If you have any real-time software, it’s best to disable it. Getting rid of these will fix the crackling problem.

Here you need to uninstall some audio software that comes on the machine, namely Sonic Master and ASUS Asio. If you have an ASUS machine and a Realtek driver, then the issue is not the driver. Here you want to find something called ATI HDMI Audio and disable that. You want to go to Device Manager and then expand Sound, Video and Game Controllers. This won’t work for everybody, but if you have it in Device Manager, it is probably the cause. If you find that disabling your network card or some other device drops the latency a lot, then you probably have to reinstall the drivers with the latest from the manufacturer’s website. Basically, you want to see green bars like above and nothing in the red area up top. On the download page, they also have an entire explanation of how to use the program to figure out which device is causing the latency. It will help you figure out what is causing the latency, such as a network adapter.

There is a cool program called DPC Latency Checker that monitors your computer’s performance in real time. You can disable it by right-clicking on the volume icon in the taskbar, choosing Recording Devices and then disabling the S/PDIF In or any other Line In port.ĭepending on your system, there could be a high latency affecting performance and thereby causing serious audio problems.
