Front headphone jack does not output audio

[osy]

The front headphone path seems to be correct but no sound is being outputted. Appears to be a codec init issue.

Linux init calls these functions:

alc_update_coef_idx(codec, 0x4a, 1 << 15, 0); /* Combo jack auto trigger control */
snd_hda_codec_write(codec, hp_pin, 0, AC_VERB_SET_AMP_GAIN_MUTE, AMP_OUT_MUTE);
snd_hda_codec_write(codec, hp_pin, 0, AC_VERB_SET_PIN_WIDGET_CONTROL, PIN_OUT);
alc294_hp_init()

Running the verbs from alc294_hp_init and then manually resetting (restarting) allows headphone output to work on the next boot. However, microphone still does not work, and sound breaks again after sleep/wakeup or headphone unplug/replug. Additionally, the audio quality is poor and requires some additional adjustment.

Fixed in https://github.com/acidanthera/AppleALC/releases/tag/1.4.2

@osy86 Should the front audio jack work for analog audio with the latest v2.4?

I see you close this saying it's fixed in AppleALC 1.4.2, but in the https://osy.gitbook.io/hac-mini-guide/ it reports Analog Audio (back port only)

Thanks in advanced :)

[osy]

It should work. Microphone still doesn't work though. I will update the guide.

[chrisallen]

Thank you @osy86 :) Should it mute the rear port when the front is connected?

[chrisallen]

Ahh I just tested, and it works in reverse. If I plug speakers into the rear and headphones into the front, audio only comes out the rear port. If I then unplug the speakers from the rear port then the front port starts working.

[osy]

Yeah I’m sure there’s a way to change that but I haven’t looked into it.

[chrisallen]

Could you reopen this GHI and edit the title to reflect the reversed behaviour? or should I raise a new GHI?

[osy]

Yeah open a new one

[chrisallen]

Thanks. I have raised a new GHI here: #144
