Default Help with I2C

I'm trying to test sending I2C commands from the Combo to a Buffalo II DAC but can't get it to work.
I'd like to ask for help any one who has made any ES901x DAC work with the update tool.
I'm using v. 111a of the Update Tools and 1072 firmware (both CPU and CPLD). Tried with and without Buffalo's on board BIOS.
I've connected pin 2 of the Combo384 to SCL and pin 12 to SDA on the DAC.

As per Domenico's instructions on post #1062 on this thread (USB to I2S 384Khz - DSD Converter)

I assigned the next for simple testing:

On88Set:
address = 0x49
register = 0xA
value = OxCF (mute)

and in case it worked I assigned the following to unmute:

On176Set:
address = 0x49
register = 0xA
value = OxCE (unmute)

Save by clicking "Write Flash"

I also tried changing address to 0x90 but same result. Playing a 88.2K file does nothing, there is music coming through so "mute" command wasn't triggered by 88k sample rate as expected.

Any ideas? am I doing something wrong?

Thx mate
Should it work with the BIOS in place? I just tested with 0x48 and BIOS in place and no effect, still getting music when playing 88.2k

Sorry not sure which Bios you are referring to here. The one in your PC? If so, probably not relevant here.
There is also normally a earth/ground connection that should go between the Combo and the Buffalo I2C connection. At least there is one in my Buffalo24. Just checked your register numbers and values against the ES9018 datasheet and they appear to be correct to mute and unmute the DAC. I take it, you have tested with a meter to make sure that the I2C wires interconnect correctly?

Sorry, by BIOS I menat the TPA firmware chip.
Haven't measured yet but I'll try doing SCL tomorrow, guess it'll be TTL 1.65V level, right? measuring data could be problematic if it produces short burts when commands are sent.
I'll also try post some pics of the wiring but I did twist each wire with a GND line joined them at the Buffalo's end.
