No sound in headphone, speaker works fine

[baptu (Rudra Banerjee)]

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:

I tried following https://fedoraproject.org/wiki/How_to_debug_sound_problems with no success.

1. alsa-info.sh --no-upload -> https://pastebin.com/P23ttY4B
2. Removing Pulseaudio doesnt change the problem
3. alsamixer -c0 -> https://pasteboard.co/JFsZ09F.png
4. options snd_hda_intel model=(recommended parameter) I dont know the recommended option

I tried pulseaudio troubleshoot from arch also, with no help.

Update I have also found:

$cat /proc/asound/card0/codec* | \grep Codec
Codec: Realtek ALC295
Codec: Intel Kabylake HDMI

and

$cat /etc/modprobe.d/sound.conf 
options snd-hda-intel model=asus-zenbook

doesn’t help either.

Kindly help.

No sound when using headphones

When i connect headphones on Mini-Jack 3.5, system does not find it. I try install pavucontrol, but it also doesn’t show headphones. Here output for 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 alsa-lib parser.c:260:(error_node) UCM is not supported for this HDA model (HDA Intel PCH at 0x98400000 irq 176) alsa-lib main.c:1014:(snd_use_case_mgr_open) erro…

Could it be the same issue?

Probably…but I havn’t got the 2nd part of his output, with alsa lib-mixer. My alsactl restore is:

In Settings i have no displayed headphones as Output Device. Not the same

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.

[baptu (Rudra Banerjee)]

Headphone is working fine on other devices.
I have only one jack. If there is a problem in jack, how the soundbar is working, as shown in the picture?

[baptu (Rudra Banerjee)]

Problem Solved. We have to choose Analogue Surround 2.1/4.0 Output in Configuration. Then its working fine.

[sideburns (Joe Zeff)]

OK, we’ve eliminated hardware; good. And, as far as the jack goes, I had no way of knowing it was good until you told me.

Please check the image again. Its before you insert the headphone. In normal speaker mode, change the configuration. Then insert the headphone.
