Comment(by lindi):
With
{{{
1) alsactl -f voice-recording.state restore
2) arecord -c 1 -f S16_LE -c2 -r22050
}}}
I see that in
{{{
runtime->hw.rates =
codec_dai->capture.rates & cpu_dai->capture.rates;
}}}
of soc-core.c
{{{
codec_dai->capture.rates == 0x00000000
cpu_dai->capture.rates == 0x000006fe
}}}
when arecord tries to open the device. It also seems that
neo1973_gta02_hifi_hw_params of neo1973_gta02_wm8753.c is not
called. If run arecord first then this function is called.
