I always do real time bounces to avoid dropouts in final/demo mixes. I can sit and listen to a mix over and over in Sonar with no dropouts whatsoever but when I bounce it to mp3 or wav I end up getting dropouts in the exported file. I always use either 256 or 320 for mp3's. I've tried archiving all of the idle tracks (midi and soft synths) but that doesn't always work. I use a brickwall limiter (UAD Precision Limiter) on the output so I'm not getting overs.
I never hear a dropout when working in Sonar. It only happens when I'm bouncing a mix. Is there such a thing as slower than real time bounce to make sure that what you hear in Sonar is what you'll get when the mix is bounced?
Any ideas?
Thanks!

Try increasing the latency.

As mentioned, you may need to increase the ASIO buffer size.
 
Also, try a non-realtime bounce.
It'll still bounce fast...
Note you may need to uncheck the Fast Bounce option (causes glitches with some plugins)

Open aud.ini and check the value of the BounceBufSizeMsec variable. If it's currently set to 30, change it to 0. If it's already at 0, try setting it to 350. Some projects might require it to stay at 0.

Try increasing the latency.

That sorted it, thanks! It makes the UI unusable but that doesn't matter for real time bounces. Interestingly, I get a crash on a pure virtual function call right at the end of the bounce when I turn the latency all the way up, it might be a misbehaving plugin somewhere in the chain or maybe a dll is getting unloaded early.

Thanks, I'll try that too. The docs are a bit ambiguous as to when to use the setting (they mention soft synth bounces), Currently it is set to 0, I'll try setting it to a higher value and see if it fixes the problem as well. If it works, it's probably a better solution than fiddling with the latency for bounces.
