Hi,
from the manual of the allo isolator:
"Sampling Frequency ranges from 8 kHz to 384 kHz"
Is there an I2S driver which supports 352,8/384kHz without any chip communication necessary?
A "bare metal" I2S out?
The generic-2 has only 24bits output, I want to use 32bit full chain, because I need the digital volume control.
It sounds dull if you lower volume a lot in 24bit compared to the 32bit chain (I have an full active high end audio system, here I can hear this differences easily).
RPI-DAC I have not tested, thought this is some kind of internal analog audio out, will test it next time I switch the system on.
The descriptions of the different drivers is ...
Yes, no way to disable the oversampling stage, but if you feed in the 8x sampling frequency there is nothing to do for this stage.
BR and happy new year,
Erich
