Cantatis Overture 192 High Performance 24-bit 192kHz Audio Interface - Page 2

There is only one problem - 44kHz (88,2,176) playback works, 48kHz (and multipliers that is 96,192) don't work properly. It's like listening to music in 'slow motion'. I guess that Prodigy 7.1 hifi has different clock on board for 48 and its multipliers.

Does it automatically change the sample rate after the mod?

Does it automatically change the sample rate after the mod?

Yes, but it doesn't matter, because it supports 44kHz sample rate multipliers only. So 44, 88.2 and 176.4kHz. Too bad. Also, don't use Vista/W2008 if you wan't to play 88.2 or 176.4 sample rate tracks. The Cantatis guys say that Vista doesn't support these sample rates. Well, I don't agree, somehow other products can do it just fine....

my guess is that they don't have an in-house drivers guy to do it.

Most of it is probably outsourced to another company.

It's not outsourced - it's basically VIA driver. Anyway, I have some great info for you!

Guys from Cantatis finally gave me some valueable tip I don't use their control panel, because it doesn't work in W2008 at all. I installed the drivers only. This is very simple tweak and for me - a life saver!!!

What you need to do is:

Search for the following registry keys in regedit (edit all of them):

VA_CPLAutoSR (set to 0 = no auto sample rate, 1 = auto sample rate)
VA_CPLSelectSR (set as follows, in hexadecimal, I set to 0x0e that is 192kHz):

0x00: 48 KHz (default)
0x01: 24 KHz
0x02: 12 KHz
0x03: 9.6 KHz
0x04: 32 KHz
0x05: 16 KHz
0x06: 8 KHz
0x07: 96 KHz
0x0E: 192 KHz
0x0f: 64 KHz
0x08: 44.1 KHz
0x09: 22.05 KHz
0x0A: 11.025 KHz
0x0B: 88.2 KHz
0x0C: 176.4 KHz


Now I don't have to change the damn thing every time I want to listen to some different sample rates stuff.

Enjoy!

Can it be done with native Cantatis driver or do I have to make a mod you've referred to?

Thanks. 

Can you elaborate on how to do in Windows 7?
