According to your description, I would suggest that upgrade your audio driver to newest version ( as I know, it is v.6.10.0.5511, A04). Also, please go to Control Panel > Sounds > Playback Devices, highlight Speakers, Properties tab, and disabled all enhancements as a test. I hope it helps. ----------------------------- Sincerely, Guozhen Wang
