What I meant was to do the following instead:
/*
* ADC PGA mix input volumes. From -12 to 0 dB in 1.5 dB steps. Disconnected
* below -12 dB
*/
static const DECLARE_TLV_DB_SCALE(mix_tlv, -1350, 150, 1);
/* Left PGA Mixer for tlv320aic3104 */
static const struct snd_kcontrol_new aic3104_left_pga_mixer_controls[] = {
SOC_DAPM_SINGLE_MUT_TLV("Line1L Volume",
LINE1L_2_LADC_CTRL, 3, 7, 15, 1, mix_tlv),
SOC_DAPM_SINGLE_MUT_TLV("Line1R Volume",
LINE1R_2_LADC_CTRL, 3, 7, 15, 1, mix_tlv),
SOC_DAPM_SINGLE_MUT_TLV("Mic2L Volume",
MIC3LR_2_LADC_CTRL, 4, 7, 15, 1, mix_tlv),
SOC_DAPM_SINGLE_MUT_TLV("Mic2R Volume",
MIC3LR_2_LADC_CTRL, 0, 7, 15, 1, mix_tlv),
};
/* Right PGA Mixer for tlv320aic3104 */
static const struct snd_kcontrol_new aic3104_right_pga_mixer_controls[] = {
SOC_DAPM_SINGLE_MUT_TLV("Line1R Volume",
LINE1R_2_RADC_CTRL, 3, 7, 15, 1, mix_tlv),
SOC_DAPM_SINGLE_MUT_TLV("Line1L Volume",
LINE1L_2_RADC_CTRL, 3, 7, 15, 1, mix_tlv),
SOC_DAPM_SINGLE_MUT_TLV("Mic2L Volume",
MIC3LR_2_RADC_CTRL, 4, 7, 15, 1, mix_tlv),
SOC_DAPM_SINGLE_MUT_TLV("Mic2R Volume",
MIC3LR_2_RADC_CTRL, 0, 7, 15, 1, mix_tlv),
};
Then, use the following instead of the "Switch" for the tlv320aic3104 interconn:
{"Left PGA Mixer", "Line1L Volume", "Left Line1L Mux"},
{"Left PGA Mixer", "Line1R Volume", "Left Line1R Mux"},
{"Left PGA Mixer", "Mic2L Volume", "MIC2L"},
{"Left PGA Mixer", "Mic2R Volume", "MIC2R"},
{"Right PGA Mixer", "Line1L Volume", "Right Line1L Mux"},
{"Right PGA Mixer", "Line1R Volume", "Right Line1R Mux"},
{"Right PGA Mixer", "Mic2L Volume", "MIC2L"},
{"Right PGA Mixer", "Mic2R Volume", "MIC2R"},
Best regards,
Benoît
