Working on a Sony Vaio notebook model PCG-R505JL with docking station and using Windows XP service pack 1 and all the latest updates.

When I go into device manager it detects a SoundMax Integrated Digital Audio sound card and the properties tab says this device is working properly.

But when I go to control panel and look at the Sounds and Audio Devices Properties it says No Audio Device under the Volume tab and then under the Audio tab the Sound Playback Default device is grayed out as well as the Sound recording and Midi music playback.

Under the hardware tab it does show the SoundMax Integrated Digital Audio and says the device is working properly.

What gives?

Tried uninstalling the device and reloading the latest drivers from Sony and still no sound. What am I missing here. Customer says the sound used to work but is not sure when it stopped working. Can not find any Bios settings that turn off the card.
