ABUBAKARR, check in device manager to make sure that your sound card shows up. If it worked before but stopped because of the update, get a driver for the HP that works under Vista [http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=ob-61386-1&cc=us&dlc=en&lc=en&os=2100&product=1842189&sw_lang=|from here.] Uninstall the device, then reinstall with the new driver. Hope this helps, good luck.
