Digitale, apparently you are not the only one. Do a Google search on that particular problem. Most of them are resolved by doing a clean install of Win Vista, let all the drivers install, then install win 7 update. Or you can try this, download the HP Compaq nx6125 Notebook PC*-* Conexant AC97 Audio Driver for Microsoft Vista (32-bit) [http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&prodTypeId=321957&prodSeriesId=471753&prodNameId=471756&swEnvOID=2096&swLang=8&mode=2&taskId=135&swItem=ob-47262-1|from here] Extract but dont install. Go to c:swsetup and rename the 2 files: camc6aud.sys and camc6hal.sys to camcaud.sys and camchal.sys and copy them to c:windowssystem32drivers and restart the laptop.
