If anyone has any objections, please let me know. ------------------ From: Christophe Leroy [ Upstream commit 6370a996f308ea3276030769b7482b346e7cc7c1 ] The gain ranges specified in Renesas IDT821034 codec documentation are [-3dB;+13dB] in the transmit path (ADC) and [-13dB;+3dB] in the receive path (DAC). Allthough the registers allow programming values outside those ranges, the signal S/N and distorsion are only guaranteed in the specified ranges. Set ranges to the specified ones.
