Hello All.  Just wanted to get a point of comparison from others regarding you Reported Latency in Sonar Platinum.  I've noticed that my Reported Latency hovers at 1750 when I first open Sonar.  This, with no project open.  I'd like to hear some Reported Latencies from others.
 
To check, open Sonar and go directly to "Preferences " without opening a project.  In preferences, click "Sync & Caching" under the Audio menu.  On the right, bottom, you will see a checkbox and "Use Reported Latency"  post your number.
 
Not sure if this has anything to do with anything, just wanted some numbers for comparison.  Maybe you could also post your default Sample, Bit Rate, and Interface type as well.
 
Here are my 96k Sample Rate details:
Interface:  Roland Quad Capture
Default Sample Rate: 96k
Default Bit Rate: 24bit
ASIO Buffer Size: 512 samples
ASIO Reported Latencies
In = 7.7ms
Out = 10.6ms
Roundtrip = 18.2ms
Sync & Caching
Playback I/O Buffer Size = 256
Record I/O Buffer Size = 256
Use ASIO Reported Latency = 1750
 
Here are my details when I switch to 44.1K Sample Rate

Interface:  Roland Quad Capture
Default Sample Rate: 44.1k
Default Bit Rate: 24bit
ASIO Buffer Size: 256 samples
ASIO Reported Latencies
In = 4.2ms
Out = 5.3ms
Roundtrip = 9.5ms
Sync & Caching
Playback I/O Buffer Size = 256
Record I/O Buffer Size = 256
Use ASIO Reported Latency = 914
 

Interface:  Focusrite Scarlett 2i4
Default Sample Rate: 44.1
Default Bit Rate: 24bit
Reported Latency (no project open) = 616

I don't think a project being opened or closed has anything to do with this. It should be the same number as your reported Total Roundtrip ASIO Latency under Driver Settings. It depends on your buffer size, sampling rate and bit depth.

if you want to compare latency, you should post numbers in ms (not buffer size) ... and it only makes sense to compare it at the "lowest playable buffer setting" i.e. either use a VST you all have and check that you can play it without dropouts or use the Sonar demo project ...  otherwise you could set it to virtually anything and its meaningless

i can set asio4all to 64 samples for my onboard realtek but it won't play ****
