Hi Team,
Can you pls give an idea about the Audio mixer paths for routing and widgets.
I have The below interconnections in tlv320aic3104 codec:
static const struct snd_soc_dapm_route intercon[] = {
/* Left Input */
{"Left Line1L Mux", "single-ended", "LINE1L"},
{"Left Line1L Mux", "differential", "LINE1L"},
{"Left Line1R Mux", "single-ended", "LINE1R"},
{"Left Line1R Mux", "differential", "LINE1R"},
{"Left PGA Mixer", "Line1L Switch", "Left Line1L Mux"},
{"Left PGA Mixer", "Line1R Switch", "Left Line1R Mux"},
{"Left ADC", NULL, "Left PGA Mixer"},
/* Right Input */
{"Right Line1R Mux", "single-ended", "LINE1R"},
{"Right Line1R Mux", "differential", "LINE1R"},
{"Right Line1L Mux", "single-ended", "LINE1L"},
{"Right Line1L Mux", "differential", "LINE1L"},
{"Right PGA Mixer", "Line1L Switch", "Right Line1L Mux"},
{"Right PGA Mixer", "Line1R Switch", "Right Line1R Mux"},
{"Right ADC", NULL, "Right PGA Mixer"},
/* Left DAC Output */
{"Left DAC Mux", "DAC_L1", "Left DAC"},
{"Left DAC Mux", "DAC_L2", "Left DAC"},
{"Left DAC Mux", "DAC_L3", "Left DAC"},
/* Right DAC Output */
{"Right DAC Mux", "DAC_R1", "Right DAC"},
{"Right DAC Mux", "DAC_R2", "Right DAC"},
{"Right DAC Mux", "DAC_R3", "Right DAC"},
/* Left Line Output */
{"Left Line Mixer", "PGAL Bypass Switch", "Left PGA Mixer"},
{"Left Line Mixer", "DACL1 Switch", "Left DAC Mux"},
{"Left Line Mixer", "PGAR Bypass Switch", "Right PGA Mixer"},

{"RLOUT", NULL, "Right Line Out"},
/* Left HP Output */
{"Left HP Mixer", "PGAL Bypass Switch", "Left PGA Mixer"},

{"Left HP Out", NULL, "Left DAC Mux"},
{"HPLOUT", NULL, "Left HP Out"},
/* Right HP Output */
{"Right HP Mixer", "PGAL Bypass Switch", "Left PGA Mixer"},
{"Right HP Mixer", "DACL1 Switch", "Left DAC Mux"},
{"Right HP Mixer", "PGAR Bypass Switch", "Right PGA Mixer"},
{"Right HP Mixer", "DACR1 Switch", "Right DAC Mux"},
{"Right HP Out", NULL, "Right HP Mixer"},
{"Right HP Out", NULL, "Right DAC Mux"},
{"HPROUT", NULL, "Right HP Out"},
/* Left HPCOM Output */
{"Left HPCOM Mixer", "PGAL Bypass Switch", "Left PGA Mixer"},
{"Left HPCOM Mixer", "DACL1 Switch", "Left DAC Mux"},
{"Left HPCOM Mixer", "PGAR Bypass Switch", "Right PGA Mixer"},
{"Left HPCOM Mixer", "DACR1 Switch", "Right DAC Mux"},
{"Left HPCOM Mux", "differential of HPLOUT", "Left HP Mixer"},
{"Left HPCOM Mux", "constant VCM", "Left HPCOM Mixer"},
{"Left HPCOM Mux", "single-ended", "Left HPCOM Mixer"},
{"Left HP Com", NULL, "Left HPCOM Mux"},
{"HPLCOM", NULL, "Left HP Com"},
/* Right HPCOM Output */
{"Right HPCOM Mixer", "PGAL Bypass Switch", "Left PGA Mixer"},
{"Right HPCOM Mixer", "DACL1 Switch", "Left DAC Mux"},
{"Right HPCOM Mixer", "PGAR Bypass Switch", "Right PGA Mixer"},
{"Right HPCOM Mixer", "DACR1 Switch", "Right DAC Mux"},
{"Right HPCOM Mux", "differential of HPROUT", "Right HP Mixer"},
{"Right HPCOM Mux", "constant VCM", "Right HPCOM Mixer"},
{"Right HPCOM Mux", "single-ended", "Right HPCOM Mixer"},
{"Right HPCOM Mux", "differential of HPLCOM", "Left HPCOM Mixer"},
{"Right HPCOM Mux", "external feedback", "Right HPCOM Mixer"},
{"Right HP Com", NULL, "Right HPCOM Mux"},
{"HPRCOM", NULL, "Right HP Com"},
};
I'm going to connect only 2 speakers at LEFT_LOP/M and RIGHT_LOP/M that's it.
Could you pls suggest routing for it?
Thanks.
