We have identified a root cause and a fix for one of the sources of Digital Audio Service overlay errors that happen after installing Update Rollup 2 for Media Center 2005. There are some Dell Media Center systems that shipped with Emuzed Maui TV tuner cards and contained drivers that were still going through the Windows Hardware Quality Lab (WHQL) certification process. The manufacturer of these tuner cards, formerly known as Emuzed and now known as Lumanate, has released updated drivers for these tuner cards that have been certified by WHQL. The Media Center team here at Microsoft was contacted by a fellow employee with a system like this at home, and he reported to us that installing these updated drivers caused the Digital Audio Service overlay to stop appearing on his system.
If you are running Update Rollup 2 for Media Center 2005 and seeing Digital Audio Service overlays, you will first need to determine whether or not you have an Emuzed Maui TV tuner card in your computer by consulting your system specifications or by using the Media Center Diagnostics Kit. This class of tuner appears with the name "Angel" in the Windows Device Manager and the Media Center Diagnostics tool.
If you have one of these tuner cards, you will then need to determine the correct make and model and download the relevant updated driver package from the Lumanate Angel driver site and install them.
Please note - this is only one possible root cause. There are other cases that we are still investigating for folks who do not have this brand of TV tuner.
I hope this helps resolve some of these issues for folks seeing the Digital Audio Service overlay problem. I apologize for the hassles that this has caused and for the time that it took us to locate this fix.
