After checking the code and datasheet, I think what we want in the second snd_soc_update_bits call is to update WM8741_DACRMSB_ATTENUATION register instead of WM8741_DACRLSB_ATTENUATION.

Signed-off-by: Axel Lin axel.lin@gmail.com --- I don't have this hardware handy, thus I only check the the code and datasheet. The bug is there since commit 992bee40 "ASoC: Initial WM8741 CODEC driver". I'd appreciate if someone can test this patch.
