|I am now booted into WinXP with a Realtek HD audio chip. I have noticed a number of items that could be a issue.|
Before I address those I have a question concerning your re-installation of WinXP.
Is the CD the same one as you have used in the past?
Did you also install any service packs or updates?
Did you try the sound immediately after the initial install?
Do you have auto updater enabled? (default)
There have been a number of posters here in the last few days with similar sound problems. I am suspecting a MS update may be causing this issue. So, I am wondering if you have allowed any updates or service packs to install.
Also, what type of re-install are you performing? A complete new install on a formatted partition, a system restore or what?
Now on to the things I noticed while in XP. When I look at the sound listing in Device Manager I see many additional listings besides Realtek HD sound.
There is also:
Legacy Audio Drivers
Legacy Video Capture Devices
Media Control Devices
I think these items have been installed by WinAmp, which I use primarily instead of Media Player. That said, you do need codecs to play sounds.
Is media player present?
Open the speaker icon by the clock by right clicking it choose properties and click on the Audio tab. What default device is listed there? If Realtek audio then look at both the volume and advanced tabs to verify all is as it should be.
Bear with me on this as you may have been down this road before. In the past I was using Windows 7 and of course all the screens are different.
There are a total of five tabs on my screen. Each one is relevant so check them all.
