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.

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...)

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

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.

Andre

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:

https://bugzilla.redhat.com/show_bug.cgi?id=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.
