maybe here ?
0x01da PSKEY_DIGITAL_AUDIO_RATE

Digital Audio Interface override for port clock rate
When acting as a master on the Digital Audio Interface, typically using I2S or DSP mode, this PSKey allows you to define the exact clock rate generated, specified in Hz.

If set to zero, BlueCore calculates the clock rate based on the sample rate and bits per sample.

i think its final clock rate = sample rate * bits per sample * 2 chanel.
in this formula i need to change sample rate

but i'll try
upd. no changes (((
