Music flickers/crackles in Windows Media Player when browsing the Internet

Hi,

 Since when are you facing this issue?

Is this happening only when you browse IE?

The first thing we can suggest here is to update the sound card drivers manually from the manufacturer’s website.

However follow the method below and see if it can fix the issue.

1. Click Start, type Sound.
2. Click Sound. The Sound Window appears.
3. Click Speakers/Headphones and then Properties.

The properties window appears.

4. Click the Enhancements Tab.
5. Click to check the Disable all enhancements checkbox.
6. Click Apply and then OK.

The properties window closes.

1. Click Apply and then OK. The sound window closes.

Another thing you can try is to Turn Off the SRS WOW effects settings in Windows Media Player.

Follow the steps below to do the same. Another user seems to have resolved a similar issue by turning off the SRS WOW effects.

1. Click Start, click All Programs, and then click Windows Media Player.
2. In Now Playing mode, right-click an open space in the Player

Tips: If the Player is currently open and you are in Library mode, click the View, then choose

Now playing to switch it to the Now playing mode.

3. Point to Enhancements, and then click SRS WOW Effects.
4. "SRS Wow Effects" panel will appear at the top. From here you can Turn off the feature.

Also I would suggest you to optimize Internet Explorer and check if it helps, here is the link:

I haven't looked but I am guessing your GT220 has the ability to output via HDMI, Hence the extra audio hardware.

Have you tried disabling the GT216?

did a quick dig, and it looks like Nvidia has been in the spot light before for causing noticeable DTC.

I haven't benchmarked my DTC.

I get some stuttering when I am playing games on my laptop.

I am just glad most games play on a video adapter that was intended for CAD and 3d modeling.

However, No Audio Stutter/Lag when multitasking TCP/IP I/O and Audio decoding.

Windows 7 x64 Ultimate

Intel Duo P8600 2.4 Ghz

2 Gb Ram  single channel

HP Elitebook 8530W

Nvidia Quadro 770m

Don't know how much time you have for trail and error, but if time allows and you have or can borrow other parts,

I would Dump the Dual Nvidia setup install a single ATI based card and do a Fresh load of windows 7 on a Spare Harddrive.

Any more suggestions???

Tried everything you suggested and music in Windows Media Player still crackles when I'm browsing in IE8.

I've been having this issue ever since we set up the PC a few weeks ago.  With my old PC it didn't occur.  I've only noticed it happening when browsing in IE8.  Let me know if there's something else I can try to see if it could be happening when other applications are used. 

I also updated the sound driver from Realtek - most current version from 2/8/10 - but to no avail.

Does the interference directly correlate to the activity LED on your NIC

Please list the hardware.

MOBO make/model

Power supply make model and age

sound and nic

are they addin cards or built on the MOBO.

Usually only see crosstalk of this type with older hardware or a when a power supply is on its way out..
