[Trisquel-users] sound not working with headphones

[cmhobbs]

I'm on an Asus Eee PC X101CH.  Generally, everything works quite well.  I'm  
having some audio trouble, though.

Audio seems to work just fine until I plug in headphones.  I can briefly hear  
the sound over the headphones and then the mute notification pops up and  
there's no sound.  I've tried various pairs of headphones.

I don't even know where to begin troubleshooting this.  Thoughts?

Thanks!
