I recently purchased an HP ProBook 4530s and I am now experiencing a periodic buzz (about every 30 secs or so) coming from the speakers during the playback of any media. The system has Windows 7 Professional 32bit with an IDT High Definition Audio CODEC card installed. No error messages displayed and all drivers are latest and allegedly working properly. I had no problems for the first couple of weeks and then allof a sudden this crops up. I have J. Rivers Media center installed and the problem first became apparent when I played music. I finally found a fix by changing the default in the media player from mp3 to WASAPI. But this does nothing to affect sound from other sources. The sound also reverts back to system speakers only when certain apps (internet and local) are launched for a short period. Any help will be most appreciated.

Hi Im experiencing exactly the same problem, i have latest drivers and averything. Its really irratating , strangley enough when you burn o disc and play on something else the sound is fine so i know its definitley a laptop issue. I get the buzz through the headphones as well . looks like a sound card error maybe??? Anyone else having problems and how did you cure it ?

Exactly as you said... thx!
I disabled the HP Power Assistant and the "buzz" sound glitches stopped.
All of this started this week. I purchased this laptop more than a month ago and this was not the case all this time while the HP Power Assistant was running.
This annoyance started right after the last HP updates through the HP Support Assistant.
Thanks & BR.

I also have the problem on a brand new 4530s.
What is the downside of disabling the hp power assistant service?

You don't need to disable the HP Power Assistant, as I have established that an earlier version doesn't cause this audio interference (rapid reverb effect). The problem can be heard on both speakers and headphones. The release you need is...
Version: 188.8.131.52 (9 Sep 2011) - sp54342.exe.
This covers most recent Win OS variants, but please verify that yours is included before installing...
PS. I recommend uninstalling your current HP PA version manually before installing v184.108.40.206
