and this will modify the HPR and HPRCOM (right channels) only.

You should add two controls:

/* HP/HPCOM volumes. From 0 to 9 dB in 1 dB steps */ static DECLARE_TLV_DB_SCALE(hp_tlv, 0, 100, 0);

SOC_DOUBLE_R_TLV("HP Playback Volume", HPLOUT_CTRL, HPROUT_CTRL, 4, 9, 0, hp_tlv);

SOC_DOUBLE_R_TLV("HPCOM Playback Volume", HPLCOM_CTRL, HPRCOM_CTRL, 4, 9, 0, hp_tlv);

};

/* For other than tlv320aic3104 */
