I have a tune I'm working on.
 
In this tune if I click on the time line while it's playing Sonar will drop out. If I click a marker in the marker list Sonar Drops out. When it drops out, a space gets it all going again. The song has 20 tracks 10 buses, superior drummer, moderate effect count.  Moreover, sometimes space won't stop it and the transport stop won't stop it but the pause button lights up and clicking it will stop and start play though the pause light never goes out. Also when it's in this condition, the rewind button and W don't work but the slider thingy under the transport buttons will rewind it all.
 
AFAIK this has been like this for a good while.
I am running 1024 buffers in ASIO mode on a TERRATEC EWS88D.
QUAD XEON Dell Precision - win 7 32bit 4 gb ram sata drives - separate audio drive and system/samples.
 
I used to run a commercial studio with this setup and THIS stuff never happened but that was back on 8.5 / X1.
 
Seems to only be this song but it's rockin and I don't want to trouble shoot the song just just wanna get Sonar to play and stop it like it should.
 
It doesn't start out doing this, just after a while, maybe a half an hour.
It also will crash alot when inserting and deleting plugs as if it's all on the rickety edge.
 
What can I tweak.  DPC is nice and steady in the green by the way.

Have you tried putting you project files on a different drive than the one sonar lives on, sounds like audio engine drop outs.

If you are having transport issues this points to your audio interface drivers and firmware. Update them. Whilst you are at it run windows update everywhere.

If you are running ASIO4ALL please uninstall it completely.

What happens if you disable all the plugins? If it works it could point to a specific plugin so rule that out.

I also suggest you check the windows event viewer for errors.

Another thing to try is latencymon.

You may need to up your midi buffers in Sonar preferences.

Otherwise with 32 bit windows the max you can address is 4gb RAM anyway. This is really the bare minimum. It could be you are on the limit and you need to consider a system upgrade.

It is an Audio engine drop out.
Sonar is on C:
Audio files on D:
 

The weird action with the transport were dying batteries on my wireless keyboard.
The "click the timeline while playing dropout" is still there and constant.

Did you bother to read my post?

Dropouts when moving the transport position during playback may be due to buffers running dry because the disk read isn't fast enough in a project with a lot of audio tracks. Have you lowered your Disk I/O buffers? I'm not sure what the default is anymore, but mine are at 256kB, and that seems to work well. A larger ASIO buffer may require larger disk buffers.

+1 to trying a change in buffer size. Too large can be just as bad as too small.

Huh. I'll try that. I recently went from 128 to the (safe and sane?) 1024 which was always my happy spot.
 
Thanks.
