Hi, are you using a sound server like pulseaudio?
If you're using plain ALSA without a sound server, you'll probably need to configure it to specify that you want to use headphones instead of, say, HDMI. I've configured ALSA so that I can use the speakers on my EV2450 monitor via HDMI: • rocketmouse@archlinux ~ $ aplay -l | grep EV2450 card 3: PCH [HDA Intel PCH], device 3: HDMI 0 [EV2450] ^^^^^^ ^^^^^^^^ • rocketmouse@archlinux ~ $ cat .asoundrc defaults.pcm.card 3 defaults.pcm.device 3 In your case...

Unlike professional or prosumer audio devices, you don't need dmix or a soundserver for these onboard audio devices so that multiple programs can access the audio device at the same time. It's really, really rare for my audio to stop working for no apparent reason. When that happens, I have to restart the computer, and then the audio works again. Does alsamixer not show headphone for your Intel device? Since I use HDMI, it's irrelevant to me, but for me, alsamixer displays a fader labeled “Headphon” (not spelled out in full). Every now and then I read on mailing lists that there are problems with onboard devices and headphones. Unfortunately, I can't offer any further insight on this, since I use professional audio devices when it comes to headphones. You might want to try a user mailing list for the Linux distribution you're using, where there's more activity than on this list.
