Yes it's called multi stream in Windows. However, extra GPIO causes
more confusion
in the driver.

Hi Marian Postevca you may want to separate the GPIO control by adding Headphone
Power SND_SOC_DAPM_SUPPLY. You may also want to change the gpio
handling function
in the acp3x_es83xx_jack_events function.
static const struct snd_soc_dapm_widget acp3x_es83xx_widgets[] = {
SND_SOC_DAPM_SPK("Speaker", NULL),
SND_SOC_DAPM_HP("Headphone", NULL),
SND_SOC_DAPM_MIC("Headset Mic", NULL),
SND_SOC_DAPM_MIC("Internal Mic", NULL),
+ SND_SOC_DAPM_SUPPLY("Headphone Power", SND_SOC_NOPM, 0, 0,
+ acp3x_es83xx_headphone_power_event,
+ SND_SOC_DAPM_PRE_PMD | SND_SOC_DAPM_POST_PMU),
SND_SOC_DAPM_SUPPLY("Speaker Power", SND_SOC_NOPM, 0, 0,
acp3x_es83xx_speaker_power_event,
SND_SOC_DAPM_PRE_PMD | SND_SOC_DAPM_POST_PMU),
};
static const struct snd_soc_dapm_route acp3x_es83xx_audio_map[] = {
