I have an Asus F5SR that I hadn't powered on for about 6 months until a few days ago. When I did use it again, it was to connect it to a TV to play a movie, with the AUDIO connected to a DVD-player with surround sound speakers. It was then that I noticed that the audio for the movie I was watching crackled. I first changed the audio to the laptop's speakers, and the audio also crackled, so the issue aren't the speakers. I then played the movie on a different system, and the audio was fine.

I then considered that the audio driver may be the issue. I have been using the Windows 7 audio driver, auto-installed at the operating system's first-RUN, with which I hadn't had any issues since then. Now I downloaded the manufacturer's audio driver for Windows 7 and installed it to see if it changes anything, but after a necessary system restart the audio crackling was now worse and constant.

Just to be sure, I uninstalled the driver and let Windows reinstall its standard audio driver, and it worked the same as before, and then I tried reinstalling the manufacturer's driver, and the increased crackling appeared again.

Upon reading about the issue through Google, I couldn't find a solution, but I did stumble over something half-useful. Right-clicking on the TASKBAR volume icon and going to "Playback devices", and then clicking the "PROPERTIES" button for "Speakers", under the "Advanced" tab in the new window you can change the quality of the sound when the speakers run in shared mode. The setting is by default at the minimum "16 bit, 44100 Hz (CD Quality)", and if I change it to anything higher and test it, the audio starts crackling as it does with the manufacturer's audio driver.

All in all, I can only see it as a driver issue. If anyone has any ideas as to what may be the cause of this, or suggestions as to what to try to fix it, they would be greatly appreciated.Good evening dirk101

I did have an issue like his before but it was not a laptop the unit is a DVD surround system but please bear with me and this was my issue.

On my DVD/surround system when I played a move I too got the crackling and this never happened before and after some checking and a close look at my wires one wire was chewed some and they would touch each other only during the movie.

When this happened we had a new puppy and he chewed one wire some and once i fixed the wire all was good again.

But point being did you try playing the movie on battery power (no ac adapter) if that doesn't work / help go into your sound options and try muting the MIC. But if on AC power this is the only time it happens look closely at the AC adapter for EXPOSED wiring.

Also mute all other sound options, if there are modem sound options, also i think W7 has a tab for enhancements where you can disable bass boost, room correction etc you can try disabling them also.

Plus if you have a bluetooth (either internal or USB one) either disable or un-plug it. Bluetooth is known for causing issues and interfering with speakers / your sound.

Hope this helps. Mike Quote from: hartbeatmr on July 21, 2012, 12:15:01 AM
