I've been looking for a week about this problem and still can't find anything, so I ask the community.
Some months ago, I buyed a new notebook : - HP dv5-1000 series - 30F2 m. b. with IDT High Definition Audio CODEC - 2 Gb ram Samsung - ATI HD3200 - Windows 7 (32bits)
audio and video drivers are updated to lastest version.
Week ago I started to get a wierd bug.
At random times, the notebook seems to freeze any sound for about a second then get back to normal. Sound freezes, if there's sound playing, it seems like it's repeating the same sound at incredible speed until the lag ends. Here's a mp3 to show you what kind of sound the lag makes :
