Restore Bass Response to Audio on Prostar/Clevo/Sager 6200..

Archived from groups: comp.sys.laptops (More info?)

I have a Prostar/Clevo/Sager 6200T Laptop.
Somebody made the engineering decision to cut the BASS response
to that of the 1" internal speakers.
There's absolutely NO BASS coming out the external outputs.
That pretty much eliminates the possiblilty of using it as an MP3 player
or anything else audio.

The spectrum analyzer on Winamp shows it's there, it just don't come out.

I expect it's a simple matter of changing a coupling cap somewhere.
Bad news is that the LM386s are tucked under the processor heat sink.
There's no possibility of probing it while running. I've not found the
ESS sound chip...maybe it's integrated into something else????
I've exhausted my ability to probe around with an ohm-meter to trace the
schematic on the
multi-layer board with parts on both sides.

Anybody fixed this problem and can provide pointers?
thanks, mike

Good question. NOt sure. I do think that a sw filter would be very
taxing on a P150. So, not likely. I did try different drivers without
any improvement.

I might ask why you don't read the original post before you rant.
Quoting from my original posting:
"There's absolutely NO BASS coming out the external outputs."

EXTERNAL OUTPUTS!!!!
