"high definition audio" is not a valid Sigmatel model number. And besides, Sigmatel doesn't offer support to end users. If you have used the "search this forum" button to look for identical threads to yours, you would have known this.
Support must come from the pc vendor or motherboard maker. So, provide the pc brand and model and/or the motherboard brand and model. We can figure out what audio chip it has from that information.
