Hi Sonar friends,
I was trying to change the audio driver bit depth but it`s impossible because the function is locked/dimmed on 24 besides the selected 64 double precision engine.
My audio interface is M Audio Fast Track Pro and I am running Win 7/64 and my Sonar is Platinum.
Any help?
 
Thank you

ASIO drivers often operate at only one bit depth. To change the project bit depth (the one displayed in the Mix Transport module) alter the "Record Bit Depth" setting in Preferences > File > Audio Data.
 
If you really want to change driver bit depth use a different driver.

Looks like you may be up against a limitation of the device:
Configurations
At 16-bit operation, the Fast Track Pro operates as a four-in, four-out device at a maximum sample rate of 48kHz, with analog and digital
inputs available:
< Analog Input 1 & 2 and S/PDIF input
< Analog Output 1 & 2 (available on both TRS and unbalanced Outputs 1 and 2)
< S/PDIF Output (mirrored at unbalanced Outputs 3 and 4)
At 24-bit operation, the Fast Track Pro operates as a two-in, four-out device or a four-in, two-out device at a maximum sample rate of
48kHz, with analog OR digital inputs available:
< Analog In 1 and 2 or S/PDIF
< Analog Out 1 & 2 (available on both TRS and unbalanced Outputs 1 and 2)
< S/PDIF Out (mirrored at unbalanced Outputs 3 and 4)
Or
< Analog in 1 and 2
< S/PDIF In 1and 2
< Outputs 1 and 2 or 3 and 4
At 24-bit operation, the Fast Track Pro can also operate as a two-in or two-out device at sample rates of 88.2 and 96kHz. Analog or
S/PDIF can be selected for input or output.

Thank you Scook and Slartabartfast, but what/where is the Mix Module please?
Thx

I was wrong, bit depth is not in the Mix Module, it is displayed in the Transport Module. Both modules are part of the Control Bar.

Ok, thank you very much!
 
Best regards
