I would be happy/comfortable to apply some patch or change in some kernel code if required. All I need is the direction as I have no idea about Linux sound architecture (pulse-audio and alsamixer implementation) in kernel.

I'm pretty sure that there must be some patch, the problem seems to be very widespread.

NOTE: Here is the description: (Could go long but I want to get it done in any way).

I initially had Ubuntu 13.04 in my laptop. After around 2 months of non-usage when I started using it again, I realized that I was getting no sound from anywhere (speakers,headphone ,etc., not even system sounds). I upgraded to Ubuntu 13.10 but issue remained the same. [The Laptop was in suspend mode last time, I don't know if that had anything to do with that]. I also suspected some hardware failure here.

At this time, I had a dual boot system (Ubuntu+Windows), I removed both of them and did a fresh install of Elementary OS - Luna (based on Ubuntu 12.04 LTS), but again I had the same issue. Then I did the following configuration and speakers started working (see alsa-base.conf snippet below), but not the headphones. When I plugged in the headphones, it did not change - sound kept coming through the speakers.

Currently, I have Elementary OS - Freya beta (based on Ubuntu 14.04) only in my system and I have the same problem. Speakers working but not the headphones. Plugging in the headphones does not mute the speakers and I get no sound from headphones also.

# Adding these lines at the end of `alsa-base.conf`, speakers started 
# working fine.
options snd-hda-intel model=laptop
options snd-hda-intel position_fix=1 enable=yes

I've tried lots options specified in other posts but nothing seems to work out. For example: like trying gnome-alsamixer for headphone-jack-sense option but there is no mention of `headphones.

I could not mention all the things I have tried out else the post may go very long and unnoticed but I will add output of any command if required.

I've attached screenshots and configuration of some basic stuff to give a start about what may be going on in my system. NOTE: Connecting or not connecting headphones does not change the behavior in any of these screenshots.

Please provide me the right direction as this is something important for me and I don't want to switch to Windows just because of this stupid bug and it seems like a common problem across all Debian based systems so I'm left with no choice if this bug remain prevalent.

  • You need to reformat this question as there code and URL Tags mixed with bolding etc. Would you like me to help you? After updating it, I may be able to offer some insight.

  • @eyoung100 I am not sure what do you mean exactly. If you could help me out in reformatting, this would be really great. Thanks a lot

    Try the following in a terminal: pactl list short locate the headphones then lauch pactl set-default-sink the-second-field-of-the-previous-command and now locate the number of the device with pacmd list-sinks and unmunte that device with pacmd set-sink-mute number-you-got-from-previous-command false.

    I would try an alternate pair of headphones, just to make sures the current ones weren't faulting on some device-attached check.

    Just in case this helps - we seem to have a conception that laptop audio is one device, that auto-detects whether to play through speakers or headphones, and indeed this is the way the factory OS is often set up. However, when I installed FreeBSD on my laptop, I actually noticed three audio devices, with the speaker being default regardless of whether there were headphones in the socket or not. I couldn't get that working either. Sorry, I just thought this might be helpful.

This might be a silly answer, but could it be hardware ? Are you sure the headphone worked in Windows ?

I've seen that the lenovo has a combo headphone/mic socket, and there are people who have reported problems using a headphone with it.

The Lenovo community has a forum article describing an issue similar to yours here. With an answer here
