Summary: alc655: low volume
Description:
I have ATI IXP400 sound in my notebook. codec is realtek's alc655. The
problem is I couldn't hear anything from internal speaker. When I plug
earphones in I hear very-very low music signal, so driver actually works
but. By the way under xp with realtek's drivers thats all right.. Is there
a way to see dump of ac97's registers under xp? May be XP driver uses some
proprietary features of alc655?
