I found on a SoundBlaster (90s)
a UDA1334A unit, I want to know if it's still possible to use it in any way.
I'm testing on the protoboard, but without success so far.
There is signal on the output 3-wire of the CS8416 (OLRCK / OSCLK / SDOUT), but no audio signal on the output of the UDA1334A.
I'm including the schematic of the protoboard, I believe it is configured for I²S, but I can not identify why it does not work.
Can anyone with more experience help?

Wow, blast from the past! I think one of my very first standalone DACs was based on a "bitstream ADAC" UDA1321 Happy Days
The ADAC enables the wide and continuous range of input
sampling frequencies. By means of a Sample Frequency
Generator (SFG), the ADAC is able to reconstruct the
average sample frequency from the incoming audio
samples. The ADAC also performs the sound processing.
The ADAC consists of FIFO registers, a unique audio
feature processing DSP, the SFG, digital up-sampling
filters, a variable hold register, a Noise Shaper (NS) and a
Filter Stream DAC (FSDAC) with integrated filter and line
output drivers. The audio information is applied to the
ADAC via the USB processor or via the digital I/O input.
An external DSP can be used for adding extra sound
processing features via the digital I/O-bus.
The UDA1321 supports the standard I2S-bus data input
format and the LSB-justified serial data input format with
word lengths of 16, 18 and 20 bits.
The wide dynamic range of the bitstream conversion
technique used in the UDA1321 guarantees a high audio
sound quality.
I thought it sounded smooth and sweet

thanks!
Resolved some bugs when power is turned on.
But still no sound.
With this configuration of the CS8416, it works well with the CS4344.
I'll keep trying ...

I miss this time.
