Hi Paul,
I tried pasting your OEMSettingsOverride.AddReg section into one of our card
drivers, did a clean reinstall on Windows 7 32-bit and it came up with 48kHz
16-bit stereo as the default speakers setting. I don’t know why it isn’t
working for you, although perhaps as you suggest it might be your use of
devcon.exe.

Hi Jeff-
Thanks for the suggestions but this is still kicking my rear, I tried following
your tips but its still not changing the default sampling frequency.
But I’m just learning how .inf files work and probably know just enough to be
dangerous and likely there is still something wrong in my .inf file.
I copied it below, if you could be nice enough to take a look at it to see what
is still bungled I would really appreciated it. I compiled this by looking at
several different examples so its very likely I messed something up.
Also I wouldn’t think this would matter, but for this development work I’m
using devcon.exe to do the installs but I wouldn’t think that would make any
difference, am I wrong about that?
Thanks,
Paul
