hi all, im using a Acer aspire 5930 here with Realtek HD Audio (ALC888S). have been using this sound device more almost half a year, getting really annoyed with the "auto gain control" function from Realtek. in the past AC97 device, the realtek has option to enable or disable this function. Now, AGC is always turned on and it really annoy my ears. for those who doesnt understand what is AGC: AGC is a software function to cut-off distortion by lowering the output level. the bad thing is, its so highly uneffective that even using realtek's own dolby natural bass will trigger this thing. sound is squashed and dragged. for quick example, play a bassy music on WMP and turn on SRS TruBass to 50% or above. you will hear the sound is dragged and squashed. while, surprisingly, an inferior SigmaTel HD audio doesnt have this feature. means when i set SRS TruBass to 50%, i can hear my speakers distort. but the sound are not "processed" hence it still sound better than the realtek one. anyone using realtek experiencing same problem? or does it only apply to realtek notebook range..
