I've applied this but there's one issue you should fix up later:
- /* mute all outputs and set PGAs to minimum gain */
- for (i = WM8983_LOUT1_HP_VOLUME_CTRL;
i <= WM8983_OUT4_MONO_MIX_CTRL; ++i)snd_soc_update_bits(codec, i, 0x40, 0x40);I know you're doing this to minimise artifacts on initial bias raise but we should really be doing this without affecting the default register settings.
Well, what about using the cache_bypass option to write directly to the HW?
Thanks, Dimitris
