I’ve recently encountered a new problem with one of the Dell XPS systems. The Dell XPS 420 suddenly loses audio output going to the speakers. If you check the sound option in control panel, the only device it detects or shows is the HDMI port. Funny thing about this is that the brand new XPS 420 does not have an HDMI port. Expansion cards installed are ATI TVTuner card and ATI HD 2600 XT video card. Both expansion cards do support Hi-Def output but they don’t have HDMI ports. XPS 420′s audio chip is from Sigmatel. If you reinstall the drivers downloaded from Dell’s website it tells you that the object/device cannot be found. The Dell XPS 420 audio works out of the box, PC-restore sometimes works but eventually it loses the audio again. I am thinking that there is a conflict with drivers on this system. Any ideas?

That did it! I got a cheapo $20 sound card from OMax, installed it and now I have sound again.

“Funny thing about this is that the brand new XPS 420 does not have an HDMI port. Expansion cards installed are ATI TVTuner card and ATI HD 2600 XT video card.”
Though the video card does not have a built-in HDMI port, all ATI HD 2xxx, HD 3xxx, and HD4xxx series cards are capable of HDMI output with audio when you use the correct DVI->HDMI adapter.
Here’s a link for one for the HD2xxx series:
