Hello,
In my asus zenbook, there is no sound from headphone.
In Setting-> Sound-> Output sound strength bar, it shows sound is there, but I can’t actually hear any:
Probably…but I havn’t got the 2nd part of his output, with alsa lib-mixer. My alsactl restore is:
$alsactl restore
alsactl: state_lock:125: file /var/lib/alsa/asound.state lock error: File exists
alsactl: load_state:1683: Cannot open /var/lib/alsa/asound.state for reading: File exists

Two questions: first, have you tried using a different set of headphones and second, have you tried connecting your headphones to a different jack, if your computer has one or a different computer? There’s always the possibility that either your headphones or the jack you’re using are bad, and if so, hunting for a software issue is a waste of time.
