I am trying to record mic with AsoC wm9713 driver. My Mic is connected "Mic 1".
My settings
'Mic A Source' -> "Mic 1"
'Mic Boost (+20dB)' [on]
'Capture' [on]
'Left Capture Source' "Mic 1"
'Right Capture Source' "Mic 1"
i am issuing following command to record
"arecord -M -f S16_LE sound.wav"
But what i found is driver is not enabling "Mic bias" and "Mic A PGA"
this dump of /sys/devices/platform/soc-audio/dapm_widget while
"arecord" is running is given below
Mic Bias: Off
Mic B Pre Amp: Off
Mic A Pre Amp: On
Mic B PGA: Off
Mic A PGA: Off
Mono In: Off
Right Line In: Off
Left Line In: Off
Mono Out: Off
Out 4: Off
Out 3: Off
Right Speaker: Off
Left Speaker: Off
Right Headphone: Off
Left Headphone: Off
Right ADC: On
Left ADC: On
Aux DAC: Off
Voice DAC: Off
Capture Mixer: Off
HP Mixer: Off
AC97 Mixer: Off
Right DAC: Off
Left DAC: Off
Speaker Mixer: Off
Mono Mixer: Off
Right HP Mixer: Off
Left HP Mixer: Off
PM State: D0
In idea why this is happening?
what is going wrong with my settings?

I've replied to this duplicate post on alsa-dev.

Liam i have few more doubts
i have only Mic1, i am not connecting to Mic2A and Mic 2B
So can i remove audio path to Mic2A and Mic2B
means
my audio path will be like
static const char* audio_map[][3] = {
/* mic is connected to mic1 - with bias */
{"MIC1", NULL, "Mic Bias"},
{"Mic Bias", NULL, "Mic 1"},
#if 0
/* mic is connected to mic2A - with bias */
{"MIC2A", NULL, "Mic Bias"},
{"Mic Bias", NULL, "Mic 2"},
/* mic is connected to mic2B - with bias */
{"MIC2B", NULL, "Mic Bias"},
{"Mic Bias", NULL, "Mic 3"},
#endif
{NULL, NULL, NULL},
};
instead of
static const char* audio_map[][3] = {
/* mic is connected to mic1 - with bias */
{"MIC1", NULL, "Mic Bias"},
{"Mic Bias", NULL, "Mic 1"},
/* mic is connected to mic2A - with bias */
{"MIC2A", NULL, "Mic Bias"},
{"Mic Bias", NULL, "Mic 2"},
/* mic is connected to mic2B - with bias */
{"MIC2B", NULL, "Mic Bias"},
{"Mic Bias", NULL, "Mic 3"},
{NULL, NULL, NULL},
};
what is the meaning of these lines, what is RXP and RXN
/* set up mainstone codec pins */
// snd_soc_dapm_set_endpoint(codec, "RXP", 0);
// snd_soc_dapm_set_endpoint(codec, "RXN", 0);
snd_soc_dapm_set_endpoint(codec, "MIC1", 0);

This is fine, it's safe to remove unused Mic's.

RXP and RXN are from a different codec and should be removed. Also
remove the MIC1 endpoint setting to 0 as this will disconnect it.
Comments from driver :-
static int identity_wm9713_ac97_init(struct snd_soc_codec *codec)
{
struct platform_controller *controller =
codec->ac97->bus->private_data;
struct aaci *aaci = (struct aaci *)controller->bus_controller;
snd_ac97_pcm_assign(codec->ac97->bus, 3, ac97_defs);
aaci->ac97_bus = codec->ac97->bus;
/*
* * Disable AC97 PC Beep input on audio codecs.
* */
if (ac97_is_audio(codec->ac97))
snd_ac97_write_cache(codec->ac97, AC97_PC_BEEP,
0x801e);
return 0;
}
AC97 beep should be disabled in userspace. e.g. alsa configuration file
or by changing mixers settings (alsactl can save and restore settings).
unsigned int identity_wm9713_config_sysclk(struct snd_soc_pcm_runtime
*rtd,
struct snd_soc_clock_info *info)
{
return rtd->codec_dai->config_sysclk(rtd->codec_dai, info,
12187500);
}
This function has been removed in current ASoC versions. It's best to
upgrade from kernel.org or from here :-

It's probably best to keep this thread on alsa-dev otherwise things
start to get confusing when cross posting occurs.
