On occasion, my Windows 7 64 bit machine will boot up apparently with no nvda synth selected. Ie silence.
It seems that on these occasions, the audio driver has not finished initialising so you do not hear the windows or nvda start sound and when I look in the nvda log it thinks it has no sound installed so moves the synth to silence.

I have tried to find a way to make Windows always load the sound drivers first, but without much success, so I wondered if there was a switch somewhere that would force nvda to assume a sound driver was there so to speak. After all the windows sounds still work, so I'd have thought nvda should as well.

Here is the part of the log concerned with this problem. Its very variable though. OK so I can reboot nvda and it will then speak, but the windows sound does not turn itself off merely due to the driver not being initialised...
