Manual said this register name is "Digital Volume Control". In this case, should I use "Digital Playback Volume" ? or "Master Playback Volume" ?
Either is fine.
+static const DECLARE_TLV_DB_SCALE(out_tlv, -11500, 50, 1);
Is this -11500 correct ? it should be -11550 ?
Should be -11600. You can check this by using an application like alsamixer and looking at the dB values displayed in the UI.
+static const struct snd_kcontrol_new ak4642_snd_controls[] = {
- SOC_DOUBLE_R_TLV("Playback Volume", L_DVC, R_DVC,
0, 0xFF, 1, out_tlv),
And here, Is 0xFF correct here ? Is it 0xFE ?
No, 0xff is still a valid value.
