Default New Firmware?

I noticed a March 2013 firmware update on the Buffalo 3 page. I've not found anything mentioned here or on TP site about this. What does it address?

We just put it up there.

There is a bug that can (sometimes) lead to a mis-mapping of internal DACs if you use I2S and the software remapping for stereo instead of installing the input jumpers. This is the result of either a quirk in ES9018 and how it deals with default register settings, and the order in which the registers are set. It does not always occur, but sometimes does, so we have a new version of firmware the prevents it from ever happening. Basically, you might get three (3) internal DACs assigned to each channel, rather than four.

If you are using S/PDIF inputs, or have installed the remapping jumpers, you don't need the firmware update.

If you need at, you can either download it for free or order a new chip ($0 + shipping).

EDIT: It also affects Mono implementations, not just Stereo.

Default Need a bit of help...

Put together my BIII with Legato 3.1

Tested voltages before connecting...all ok:
5.25 V for BIII rock steady.
+- 12 V for Legato 3.1.

SDTRANS had been playing for ages with SPDIF and a TDA1541 DAC so ..tested!

Now connected i2S via UFl cables...mute and lock leds cycle once on boot up them lock remains on when SDTRANS is connected so...ok.

Connected so :

SDTRANS BIII

LRCK D1
SDAT D2
DCLK DCK
GND GND

But... all i get is dead silence.

I did check balanced output Dc offset...adjusted ok to 0V.

I have set up the underside straps according to Bunpei's suggestion to emulate BII:

1 . shunt JDSD1 and JDSD2.
2 . Wire D4 to D6 on card edge.
3 . set SW2-8 ON.

I should now be able to play PCM and DSD tracks with BIII detecting automatically.

I did put the strap on ADC to connect 3.3V to PB4 not to use internal volume control.

All switches on SW1 and SW2 are OFF except SW2-8 ...that is ON.
Also soldered straps J1,J2,J3,J4,J5,J6,J7,J8,J9,J10,J11,J12

But as i say...all i get is perfect silence except tiny "pop" when lock cycles on and Off.

Since this is the first time i test a BIII i tried to research as much as possible but...no dice.

Any help welcome.

Default New Firmware

Just a note.

Anyone who got the latest firmware update needs to know that the switch states are reversed in this release to work around a bug related to the port expander.

Otherwise the setting are the same as the integration guide.

This makes it work more like the B3SE which also used the reversed switch states for the same reason.

Sorry for not mentioning this earlier on the site.

Cheers!
Russ
