weird problem with Crystall WDM audio drivers

[Paul]

Hi

I hope someone can help me diagnose a problem with sound from my Acer TM
C112 tablet pc. About a week ago, I stopped getting any noise out of the pc.
It won't drive the internal or external speakers or headphones. I ran
through all the tests in the so-called 'help and support' topics. I have
looked at the setup in device manager and it reports that everything is
working properly.

I tried reinstalling the drivers from the Acer support site and, euraka!,
the sound was working again. Only, when I rebooted, it went back to being
broke. Situation now is that I can have sound after I reinstall the drivers
and before the next reboot.

I have been messing around with the box installing new software and
generally adjusting system settings. It seems likely that one or other of
these processes has caused the problem but I have no idea what. I have tried
turning of the new software and stopping various things loading on start up
but it hasn't helped.

Has anyone any advice on:

what could be causing the problem, or;
how I might go about diagnosing it, or;
a website, group etc where more information might be available.

Thanks

Paul

Conflicting audio codecs or drivers, can't recall which. Happened to me, I
think with a DOS ESSolo driver that came along with those I downloaded. (DOS
drivers loaded at each startup?) Believe I uninstalled or disabled the DOS
drivers to fix it.
Anybody recall this conflict?

What new software?

What new software?

Can't exactly remember now but the two most likely villains are Gemplus card
reader software (goes with a PC card security card reader) and Vodafone's
Mobile Connect software (again linked to new hardware - in this case the 3G
card). Other than those, I'm mostly talking about upgrades to stuff like
Nokia PC Suite and the Yahoo desktop Widgets thing.

Any thoughts?
