Hi,
my desktop computer has one of those front headphones connectors, and it always worked (always = since Fedora8), playing the same audio that goes to the front speakers. I tried it today and it doesn't work anymore, my guess is that some of the recent updates might have changed something on audio config (I know hardware is ok because system is dual-boot, and headphones work on XP). Front speakers are working as expected.
I tried playing around with PulseAudio settings, but didn't get anywhere
I know this is a lame call for help, but I don't even know what kind of info I should provide. Here's something that might help:
# cat /proc/asound/cards 0 [Intel ]: HDA-Intel - HDA Intel HDA Intel at 0xa3220000 irq 22
System is running Fedora 9 with latest updates.
Any help will be appreciated. Let me know what kind of additional info I should provide.
Regards,
Andre

Open up the volume controls and see if there's a separate volume control just for the headphones. You might have to wallow through the preferences to add more controls.

You might look through /var/log/yum.log to see what's been recently updated, and see if they're a likely cause.

Thks for the tip, but I had already done that. There's a chekcbox for headphone, which is checked. I also tried playing with every track volume level that seemed reasonable, but it did not work.
(if anyone can provide more info on any specific settings that would affect headphone sound, that'd be great...)

I took a look, but thet fact is that I can't precise when it stopped working, so the timeframe could be long... =(
Thks anyway for your help.

Just a quick update: it's a bug with the lastest kernel. Headphone works with kernel 2.6.26.6-79. I filed it as bug #472317:

In fact, this happened to me when I upgraded to alsa driver 1.0.18. Going back to alsa-driver 1.01.7 solves the problem. I think your kernel is using 1.0.18, and I doubt anyone is going to fix it.
The only option is reporting in the alsa-devel list , and maybe someone there can do anything about it.

Well, after some work, we found out that alsa 1.0.18 (snd-hda-intel) is testing if something is plugged to the front panel, to cut the sound on the back. Unfortunately, some boards only detect the presence of jacks connected to the back of the computer. Plugging, say a headphone, to the front does not change anything. Therefore, the sound on the front of the computer is never activated.
I will test an alsa patch for my codec soon. But maybe other codecs were affected too...

In some computers, there's no "detecting" at all. It's a mechanical switch in the headphone socket, and the front and rear panel sockets are often different (e.g. a simple one on the front).
Detecting a connection made to *any* socket, without requiring special sockets, would require electronics designed for that (detecting a DC change, impedance loading change, etc.).

Hi, Tim
You are right.
In fact, the problem was my computer case connectors, for the front panel. I found out later that there are two types of Header connectors: AC97 and HDA. The new standard, HDA, allows jack detection. But the majority of computer cases still come with the old AC97 Header, which does not allow jack detection:
Please, see figures on page 20 and 25 of the link below.
http://www.formfactors.org/developer/specs/A2928604-005.pdf
The good part is that Takashi Iwai (alsa developer) introduced new "models" for some codecs, which allow the use of the front panel, even without jack detection.
The alsa snapshot I am using right now, fixed all my problems. I can hear both, the speakers on the back and headphones on the front, simoutaneously, each one with a different mixer control.
I think these new drivers will be available for the public in the next alsa release.
I had the same problem with Fedora 10. The headphones didn't work after an update I did yesterday (Jan 6, 2009). I have currently alsa driver version 1.0.8. They were shipped from the start with Fedora 10, so that it seems that the drivers were not the problem.
Then I tried to use the previous version of the kernel and now the headphones work again!!
The previous version that works OK is: 2.6.27.7-134.fc10.x86_64 The version that doesn't work is: 2.6.27.9-159.fc10.x86_64
This thread in the forum helped my A LOT.
Thanks,
Mario
