The Audio chipet is a Realtek ALC 5621 and this is what I can find in my
kernel driver:
static const char *in_sw_control_texts[] = {
"OFF", "MIC_normal", "MIC_ringtone", "MIC_incall", "Headset_normal",
"Headset_ringtone", "Headset_incall"
};
static const char *fs_sw_control_texts[] = {
"7.35kHz", "8kHz", "11.025kHz", "12kHz", "14.7kHz", "16kHz",
"22.05kHz", "24kHz", "29.4kHz", "32kHz", "44.1kHz", "48kHz"
};
static const char *out_sw_control_texts[] = {
"OFF", "Speaker_normal", "Speaker_ringtone", "Speaker_incall",
"Earpiece_ringtone", "Earpiece_incall", "Headset_normal",
"Headset_ringtone", "Headset_incall"
};
but I'm not really sure how to use these controls, in audio/audio_hw.c or
audio/audio_route.c code...
