[SOLVED] no sound in headphone jack

jyoung · Guru Joined: 20 Mar 2007 Posts: 440

Hi Folks,

I'm in the weird situation that the internal speakers on my machine work fine, but I'm not getting sound through the headphone jack. When I plug in headphones, the internal speakers go silent but nothing comes through the headphones. I know that it's not a hardware problem because when I boot off a boot disk with mplayer on it, the headphones work fine. I've checked all the settings in alsamixer, and everything seems turned on.

This problem started shortly after, possibly simultaneously with, an installation of pulse audio. However, when I uninstalled pulseaudio out and deactivated consolkit, the problem persisted (I've since reinstalled pulseaudio).

Any ideas?

Hi, jyoung!
I'm with the very same trouble! I use XFCE and I have removed pulseaudio stuff, but the problem is earlier than pulseaudio.
I've tried to recompile the kernel (3.14.4 ck) with other sound options than default, with no success.
I'll be following this thread closely!

Actually, I'm running XFCE too, and I've also looked through my kernel sound options based on what I've found in similar threads.

HerrSchafer, when I run

i have one box that the channels are always muted after starting the box. And i wont bother fixing it as i just unmute it in alsamixer and it works

run alsamixer and check if they are muted. Alsamixer will give you some informations on the status

The channels are usually muted on bootup. The responsible for setting it back to "normal" (whatever settings you had before the last shutdown) is the alsasound service, which needs to be added to any given runlevel.

What a shame! Sorry for my mistake.

Hi Folks,

HerrSchafer, I've given your suggestion a try with alsa-utils (already emerged) and adding alsasound to my default runlevel, but with no effect. It sounds like our setups are so similar - can you think of anything else that you changed in your configuration?

A few of you suggested that maybe the headphone jack was mutted by default at bootup, and that I could unmute it with alsamixer. I regularly use alsamixer to adjust my sound levels, and I noticed that back when I first installed pulseaudio the layout of alsamixer changed. Rather than having many playback channels, there's now only one. I originally assumed that it was the master channel, but perhaps the headphone jack channel really is just muted.

Does anyone know why alsamixer might offer only one channel after pulseaudio is installed and, that being the case, how could I unmute or adjust the headphone jack channel?

Assuming that pulse is not running, the settings are controlled by the .asoundrc in your home dir. So, erasing that should reset it to the default state. There might be global config files in /etc. I have no idea if pulse also breaks those. Never used it. Never understood what's about.

That, aside, assuming pulse is no longer in your system. If it is, then I have no idea.

@jyoung

I cannot find the thread from where I readed the steps I've followed... I'll look for it.

i92guboj, I currently have pulseaudio running. Before my first post, I did try an experiment where I unmerged it and turned consolekit off. When I tried that, the headphone jack still produced no sound, so I re-emerged pulseaudio and added consolkit back it.

One curious thing, though: while I had pulseaudio unmerged, alsamixer displayed many playback channels, just as it had before.

Also, I looked in my home directory, and there's no .asoundrc file - should I create one?

Well. As said above, I can't help with pulse 'cause I know nothing about it. Sorry.

Well, I kicked pulseaudio of my system... May Be because of this, it worked for me and not for you.
And I'm very excited about kicking also the *kit brothers...

Hi Folks,

The main reason that I installed pulseaudio in the first place was that it's used by the current version of skype. But, the gentoo skype wiki suggested an alternative, and given the problems it seems to be causing I decided to pull it out.

When I first installed it, I was having some trouble getting it work with skype, so I put the pulse flag in my global USE flag in /etc/make.conf. I don't normally do this, but it seemed that pulseaudio is linked to quite a lot of other systems. When I began the process of pulling pulseaudio out, I removed this flag and did a system update. When I did this, I regained the use of my headphone jack without breaking skype.

It seems that the root cause of the problem was putting the pulse flag in the global USE variable - I think we can list this thread as 'solved'. Thanks everyone for your input!
