Title: ASIO Output 16 bit on 24 bit DAC?
Post by: syn-ack on May 31, 2013, 08:43:50 am

If I have a 24 bit DAC, shouldn't MC using ASIO be outputting 24 bit?

Your ASIO driver requests a buffer format and bitdepth (ie. it's not controlled by us).

Some Cmedia (and possibly other) drivers allow picking a bitdepth in the driver control panel.  Personally I think this is silly, since the driver should always request the format that most closely matches the input of the DAC.

I have specified in control panel > sound > headphone rig (what I renamed the particular output device to) > advanced to use 24/192. But MC says output is 16 bit.

If I switch to WASAPI, it outputs to 24 bit (padded)... Of course, at the moment WASAPI is not working properly, getting that flutter/ticking sound... But I'd rather be using ASIO anyways if possible, just not sure why it isn't outputting correctly.

The ASIO driver control panel I'm talking about is normally accessed with:
Options > Audio > ASIO > Output mode settings... > Open Driver Control Panel...

Or through a system tray icon.

Only settings I can find are in the below screenshot. I don't have any other place in CP, nor a Systray icon.

Now I am wondering if I am missing something... WASAPI seems to output properly, but like said, currently has the flutter issue.

My bad, here is what I have in MC options..

Note though, the ASIO Control Panel dropdowns are greyed out, and do not allow a selection.

Disregard, I'm an idiot... You must stop playing music to change ASIO control panel settings.. I am all set now!

Thanks for the help Matt, as always you rock!
