Hi there, first time caller so apologise in advance for being a nube. I recently reinstalled XP but I have no sound. Ive tried various speakers and headphones. Ive tried reinstalling drivers. Ive got screen burn on my retinas from staring at device manager and Ive tried shaking my first at the patch of sky I think God lives in. Sound and Audio device properties shows "no audio device" and hardware shows microsoft kernal audio spliter & acoustic echo - "cannot load the device driver for this hardware because there is a device already running (code 42)". Device manager shows them both with yellow "!". Ive uninstalled and rebooted/reinstalled pretty much everything in Sound,Vid & Game Controllers. It also holds audio codecs, legacy audio, legacy video, media control, MPU 401 compatible midi, soundmax integrated digital audio, standard game port and video codecs. Found the manual for Asus K7 DDR barebone system and tells me its SiS 7012 audio driver. CPU is AMD Athlon XP & ASUS A7SC with a SIS740 chipset Probably something really dumb Im doing as far from being an expert, have just downloaded Everest as read it may be useful.
