Strange flanger noise when playing

[Azurlake]

Hello, I've noticed that when I start to play any audio file (either an audio CD or an MP3 file), either under Windows or Linux, there's a low flange noise barely noticeable that lasts for a few seconds. If loud the volume, then it becomes evident if you pay some attention. The noise I describe it like a flange noise, since it's like a very low "ggghhhshhhh" going up and down like a changing phase thing, like two audio tracks playing almost at the same time but one of them fix in speed and the other one with little variations making that sweeping flange or phaser sound -I hope you know what I mean. If I scroll back to the beginning, the noise dissapears, but now I know it's there, it has become quite annoying and I always hear it.
Has this problem been listed yet? Any other people having the same problem? Using another player I won't get that noise.
By the way, I just use an HP laptop, dv6 1360ss pavilion with those realtek HD audio drivers, and this happend under Win7 and Ubuntu9, so it's not a OS problem I assume. I use also a TC Electronic 1394 audio card but can't say now if that's still happening, anyway I would like to listen to music (neat) without having to plug it.
Cheers,
Danny.

Try to disable audio time stretching from the preference in case there is a problem with the filter.

You can also try to force the VLC audio rate to 48kHz, in case there's something wrong with your audio card (many recent cheap cards don't like 44,1kHz).

The flanging is caused by 'high quality audio resampling' option. When this is active you will get the weird flanging sometimes. Very annoying, I agree. For me, it only seems to happen with MP3s. My preferred format is M4A, so I don't encounter the bug often. What's worse, after you untick the option the sampling reverts to a crude, poor quality method that's noticeably worse compared to playing the MP3 in other players like Windows Media Player.
