Tool/software:
Hi,
Issue description: Initially, our device could operate at a 48k sample rate and consume up to 38W of power. However, it was unable to operate at a 96k sample rate.
A TI engineer provided an below initial setting, which allowed the device to operate at 96k but limited its power consumption to 10W.
Increasing the power consumption beyond 10W resulted in distortion. Do you have a recommadation on it.
