Integer mode debugging build
« on: October 28, 2013, 05:03:07 pm »

You can download a special build of MC19 Mac here that will help us debug integer mode problems.
http://files.jriver.com/mediacenter/channels/v19/latest/MediaCenter190066.dmg

Only use this build if integer mode is not already working correctly for you.

Turn down the hardware volume when testing, because wrong values will sound like noise.

In Options > Audio > Device settings... > Integer debug, try these values (enter only the number, stop playback and restart each time):
32  (32-bit data, no padding, little-endian)
524320  (32-bit package, 24-bit data, little-endian, padding in LSB)
8912928  (32-bit package, 24-bit data, little-endian, padding in MSB)
655392  (32-bit package, 24-bit data, big-endian, padding in LSB)
9044000  (32-bit package, 24-bit data, big-endian, padding in MSB)

The values will be used when doing integer mode playback to override the setting we're currently building from the system.

My hope is that one of the values will sound correct.

The Wavelength Crimson resulted in distortion in integer.

The Wavelength Crimson resulted in distortion in integer.

If you'd like to help, please report the results after entering each of the five numbers above.

Thanks.

I have tried them all and restarted MC19 every time - to no avail unfortunately  :'(

I had distortion with all of them.

I also tried all the values with the Wavelength Crimson as instructed. They were also distorted.

Sorry everyone.  This is a mystery to me.

We'll get a DAC that uses this padded format in house soon and figure it out that way.

Thanks for all the help so far.

Hello Matt -

I tried all the settings with my MSB Analog DAC, unfortunately all settings resulted in distortion. Thanks for continuing to find a solution, it is much appreciated.

I believe this build will work in integer mode with many more devices:

Testing appreciated.  And thanks for everyone that's helped us work through this.
