The earpiece is routed through RX MIX1 similarly to the headphones, except that RDAC2 MUX is set to RX1. Signed-off-by: Stephan Gerhold --- This patch is based on code from the downstream driver (msm8x16-wcd.c, [1]) with some cleanup. This enables the earpiece on the Samsung Galaxy A5 (2015), which has recently gained mainline support in [2].
