I'm installing my drivers using devcon and normally I'm removing the old
drivers before this by using devcon remove. So probably the driver is
completely removed and no settings will persist. Now I did a test without
calling devcon remove. This results in two instances of my driver. In device
manager both instances show the new version of the driver, in the sound
properties the old version keeps the sample format (44.1 kHz, 16 Bit) while
the new version is set to 48kHz, 24 Bits according to my inf. But the volume
doesn't persist for the old driver and is set to 100 for both instances.
The way to remove the old driver seems the better way to me and so I'd like
to know if there's a way to set the default format only via the signed inf
file or also after the driver installation but still inside my installer
i.e. by setting the corresponding registry entries?
Thanks and best regards,

during/after driver installation
Do other settings persist across driver version upgrade, e.g. volume?
