No Audio

Is there anyone encounter similer situation:

- there is no sound output from the XPE
- when clicking the Sound & Audio Device in Control Panel,
it reports missing MMDRIVER.INF
- in volume setting, it reported no audio device

I did notice that the following driver missed when I
imported the TAP file:

VIA AC'97 Enhanced Audio Controller(WDM).

The closest match in the component database is:

VIA AC'97 Audio Controller(WDM).

So I added this driver into the image. However, it did
not work.

I wonder this is the driver problem or not. If the driver
is the problem, where can I get the correct driver
component. Or is there anyway to modify the existing
driver component for it?

Regards,
Henry
 
Heny,

Are you using a VIA EPIA Board? If so I use the board in my class and it
requires the same audio components. You will also need add the audio codecs
for audio to work.

Henry,

TAP is picking up the AC 97 codec that is on the VIA 8235 southbridge chip
(www.via.com.tw). Your tap output should have the Realtek audio chip in the
list, but for both chips XPe doesn't come with a driver in the database.
When you PMQ import there should be a warning telling that a component is
not there. You will have to create a component for the Realtek chip.

Hi Sean,

I found the ALC650 driver on Gigabyte web site. It is
installed and worked on the XPE. I am looking into
componentize it.

Thanks
Henry
