The new value in snd_soc_update_bits() needs to match the mask bit fields. Use CS42L56_MUTE/CS42L56_UNMUTE only works when the mask is 0x01.
Signed-off-by: Axel Lin axel.lin@ingics.com --- For example, *Both* below calls actually *clear* CS42L56_LO_MUTE_MASK bit (0x80).
snd_soc_update_bits(codec, CS42L56_LOB_VOLUME, CS42L56_LO_MUTE_MASK, CS42L56_MUTE); snd_soc_update_bits(codec, CS42L56_LOB_VOLUME, CS42L56_LO_MUTE_MASK, CS42L56_UNMUTE);
So I think use CS42L56_UNMUTE/CS42L56_MUTE is not good here.
Hi Brian, I don't have this h/w, so this patch needs test. I'd appreciate if you can review and test this patch.
