"An error occurred while starting playback" !!!

After spending a morning adding subtitles in the Timeline, I suddenly keep getting this message when trying to play the timeline. Clicking Details reveals "The playback device Microsoft Sound Mapper does not exist."

Well, firstly, I have an external USB Quattro Sound Card selected as my device in XP, and anyway, I cannot find anywhere in DVDA where one selects an audio device, so how can I tell it to stop looking for Microsoft Sound Mapper?

I've rebooted but the problem currently persists - I sometimes get similar hassles from Vegas but this always goes after closing and reopening.

Any ideas what's going on??

Going purely by memory, I *think* I used to set Vegas to the Mapper as default just for this sort of thing, switching ASIO on in Vegas as needed, then turning it back off - I believe DVDA uses some of the Vegas registry settings, and that was one of them?

Sorry I can't give any more info than a cloudy memory that may be very inaccurate after all... I had the problems years ago, adopted the procedure of just switching to the mapper before existing Vegas, and have done that since through upgrades of software, drivers, and hardware. I just booted from Vista back into XP, and can't duplicate ANY problems now. Though I am using the same Sound Card (an old Audigy 2 I bought for Vegas when it 1st handled 5.1), I'm also using new drivers, latest DX 10, and HD/HDMI audio, so somewhere in there it's apparently no longer a problem.

The only other guess that occurs to me at the moment is to un-check always use default devices in Control Panel -> Sounds... -> Audio.

Thanks for the response MPM. I always have Vegas, and in fact every setting I can find set to the USB Quattro, but I'll try switching to mapper for trial purposes - I haven't even got speakers attached to my PCI sound card - I'll have to find some ... I always use the Quattro and a Behringer Mixer, but there are often times when Vegas or DVDA loses contact temporarily - it also seems related to memory sometimes.

I already have "use default devices" unchecked, so it's not that. It's frustrating not being able to work for more than a few minutes before playback stops, but if it will work with Mapper, that'll do me until I start mixing the audio seriously.

edit - yes, that works - Thanks - plugged some speakers into the souind card, changed sound device to "Sigma Tel Audio" (not PCI - it's on the motherboard!) and the DVDA Timeline has played back reliably during subtitle creation - only 100 minutes (of audio track) to go!!
