Installing VLC Media Player voids your speaker warranty
As the main developer of VLC, we know about this story since a long time, and this is just Dell putting crap components on their machine and blaming others. Any discussion was impossible with them. So let me explain a bit...<p>In this case, VLC just uses the Windows APIs (DirectSound), and sends signed integers of 16bits (s16) to the Windows Kernel.<p>VLC allows amplification of the INPUT above the sound that was decoded. This is just like replay gain, broken codecs, badly recorded files or post-amplification and can lead to saturation.<p>But this is exactly the same if you put your mp3 file through Audacity and increase it and play with WMP, or if you put a DirectShow filter that amplifies the volume after your codec output.
For example, for a long time, VLC ac3 and mp3 codecs were too low (-6dB) compared to the reference output.<p>At worse, this will reduce the dynamics and saturate a lot, but this is not going to break your hardware.<p>VLC does not (and cannot) modify the OUTPUT volume to destroy the speakers. VLC is a Software using the OFFICIAL platforms APIs.<p>The issue here is that Dell sound cards output power (that can be approached by a factor of the quadratic of the amplitude) that Dell speakers cannot handle. Simply said, the sound card outputs at max 10W, and the speakers only can take 6W in, and neither their BIOS or drivers block this.<p>And as VLC is present on a lot of machines, it's simple to blame VLC. "Correlation does not mean causation" is something that seems too complex for cheap Dell support...<p>Maybe Dell should advise against playing Metal music and should only allow Céline Dion music, because Metal saturates more...<p>EDIT: more details...<p>PS: they even provide a BIOS update for the fix... So, of course, VLC was the issue... <a href="http://www.dell.com/support/troubleshooting/us/en/04/KCS/KcsArticles/ArticleView?c=us&l=en&s=bsd&docid=557836" rel="nofollow">http://www.dell.com/support/troubleshooting/us/en/04/KCS/Kcs...</a>
