Speakers work, headphones don't


Hi All;

Also posted on openSUSE forum. Hope this is the correct subforum. As the title says, I get sound from my speakers but not from my headphones. All mixer settings are at 100% and the speakers are muted when the headphones are plugged in.

Code:
root@laptop= /home/tom # lspci

Do the headphones work elsewhere? mp3 player, other computer, etc
Do you get any sound through the headphones by moving the connection in/out/side-to-side?
where are you plugging the headphones into? the speakers themselves or the MOBO/case?

in your mixer make sure they are enabled if you want speakers and head phones at the same time also set up your sound mixer for that. Now if you never did this and it is from the original install. you should go delete your /etc/asound.state file and reboot this will actually make alsa and the system load that hda card. and re-write the /etc/asound.state file.
when you install the system it has a default guess method. and that card has caused troubles during installs. Now you will see a few more things in your mixer. especially if you have a laptop.
then open your alsa mixer make sure it is enabled and then check pulse. pulse just reads alsa. this has been my fix on many of the computers. and it is well documented.

Thanks for the replies. I know the headphones work after plugging them into my wifes' desktop. Also checked the mixer and alsa settings and nothing set to mute and all full volume.

I only noticed this behaviour recently as previously I used my laptop mostly in afternoon and early evening and used the internal speakers. Now I'm reverting to working late at night when the wife is sleeping so tried to use the headphones.

A couple of people on the openSUSE forum said to use the alsa-info.sh script to obtain information about sound system. Trouble is that alsa did not install that script during installation and haven't been able to find where to get it. Any ideas?

Sometime later this week I'll be installing some other distro and will test it on that.

Thanks, Tom
