I suspect that maybe not many ppl have expereince of the sta013. I had
to google it to find out what is was.

I'm familiar with I2C, serial audio data and although haven't yet used
SPI am familiar with how it works ( since I'm looking at a device with
an SPI i/f for a potential project ).

I have however no idea from your post exactly what problem you're
experiencing.

What data is it your shifting from I2C to SPI ? And why ? Note that " It
seems that the I2C interface is OK" suggests you're not totally
confident.

If you've got some data_req stuck low - clearly that device isn't seeing
what it's expecting ( suggesting transmission error ).

A block diagram ( even verbal description ) would help.
