It seems to affect things like certain human voices, violins, etc; I can't make out any problem with deep bass, or high treble. It's hard to describe, but it sounds like a speaker being slightly overdriven and therefore "rattling", or perhaps like slight feedback noise. It's not a problem with the laptop speaker: it's noticeable with output to a regular (fairly hi-fi) music system, as well as with headphones. There is no problem with sound from an audio CD (output taken from the same headphone socket). But ripped audio (the raw wav file, and .ogg files) from the same CDs has this distortion. So do downloaded mp3 and shn files. Is it probably just bad hardware, or could there be a problem with the sound driver? I erased windows from this machine a while ago (before I realised this problem), so unfortunately I can't compare. I'm running -STABLE from Aug 14 or so.
