12.04 distorted sound in headphones

[bbb13]

i'm facing this problem: when i connect the head phones in my laptop suddenly the sound becomes distorted and heard from beyond space. the internal speakers work flawlessly. pulseaudio is not in my system, i use alsa only.

specs:

OS: ubuntu 12.04 with gnome 3
Laptop: Sony Vaio VPCEJ1L1E
sound card: Conexant CX20590

any ideas?

I am having the same problem (Sony viao vpcf115fm) with distorted headphone sound, unless I turn the volumn down very low. No luck solving this yet myself. Have you had any luck yourself?
