I2S clock

l0v3r · Jan 12, 2005, 09:53 AM

Is possible to change the I2S clock input of Audigy2 from 96Khz to 48KHz with kX Drivers? If yes, where exactly is the option?

10x guys

see ja!

This is EXACTLY the question i wanted to ask!

Question for Eugene:

From what exact register(s) you get these values in SPDIF/I2S Status window:

I2S Inputs: (0): 96000Hz [R] (1): 96000Hz [R] (2): 96000Hz [R] ? ? ?

Any way to acces these register(s) from console?!?

Anything on this?!?

the 76 register might help you, but in most cases this causes serious issues with the p16v core... i2s inputs should be locked at 96kHz

76 register: just open the console and try to switch spdif sample rate -- you will notice 76 register changes. values for i2s are the same

440
880
cc0
etc.

Thanks!

to Eugene:

I knew about register 76, it can set p16v PB, I2S Out and SPDIF Out freq...
btw, What is p16v PB?!?

WHY i2s inputs should be ALWAYS locked at 96kHz? Is this hardware limitation?
From what register, if any, you actually read I2S Input values?

So many questions...

(С Новым годом!

to l0v3r:

Maybe you should try executing sptr 76 0 8880 or sptr 76 0 1110 comands in Kx console & check how Live! Drive input works after these...

Just before wanted to go to sleep i tried this command:

sptr 76 0 80008880

Whoops! It changed all I2S Inputs to 48000Hz (!) status

when removing highest bit from register 76 (sptr 76 0 400) I2S Inputs fade back to 96000Hz [R] in few seconds...

Eugene, what are these (!) and [R] stuff mean?

l0v3r:

Please try sptr 76 0 80000400, your Live!DriveIR might work fine with this...

10x a lot guys

, I'll try these commands this weekend, waiting for the ICs to modify the Drive.

see ja!

l0v3r · Jan 14, 2005, 05:46 PM

OK, I've done some tests right now and changing the 8th bit to 1, the info says that the I2S is set to 48KHz but the inputs mutes completely.
I forgot a thing about the UDA1360, it works at maximum at 20bits... I'll continue to do tests the next week after changing them with the UDA1361.

さようなら。

Samir · Jan 14, 2005, 08:55 PM

Hmmm, doesn't work!?! Too bad!

Also try, sptr 76 0 80008880 maybe it might work... Tried 8880 & 1110 values ???

がんばって。　

l0v3r · Jan 15, 2005, 12:19 PM

Ummm, I'll try also these settings... the next week

...

thank you for now.

happy hacking

actually, I cannot disclosure this information, since it is not available for the public. but you can figure this out yourself, I'm sure.

note that xxx0 is much close to what you need, while 80000000 will cause some unexpected behaviour.

PB is 'playback'

the 76 register's 'p16v PB' value is updated automatically whenever you start/stop playback via 'Wave HQ' device
