Studio 1535 poor audio quality under XP
Hello all.
Just installed XP Professional (we have corporate license) on my recently bought Studio 1535.
Have some troubles, the most frustrating is the sound quality is very bad.
Not only using internal speaker.
When i've connected notebook to my audio system, i had dissapointed very much.
Very strange sound, no bass at all, poor stereo.
Experiments with EQ in Intel's IDT control panel had no success - only setting all lines to maximum makes sound slightly better.
I've switched system to my old notebook - everyting was much better.
I've connected it to desktop system having SB Live 5.1 on it - sound perfect.
Connected back to Studio - oh, it awesome. My Nokia phone sounds better.
The question is - does this laptop sounds equally under Vista too ?
Is it hardware or driver problem, i mean ?
Yes,i've installed driver for XP, it works perfect except sound quality.
Plz, can somebody who has 1535 with Vista installed tell me - are there normal sound present from stock Intel's sound card ? Is there bass at its output (not on internal speakers, but using external acoustics).

"Yes,i've installed driver for XP ...."
But which version is it, or what model was it meant to be for?
Jim
It was the only driver for IDT High Definition Codec for XP i've found - 5.10.5615.0 dated by 14.09.2007
Later drivers and packs from dell, Sigmatel or other laptop manufacturers are incompatible - they haven't
VEN_111D & DEV_7675 codes in INF files.
Drivers for Vista are incompatilble also - Error Code 10 occures.
Please tell me somebody - are sound under Vista perfect ?
It is the only problem i have now, everything else seems work good.

There have been a number of posts about problems with the 1535, mainly about a glitch with the back headphone jack. However I don't remember seeing any complaining about poor audio quality through the output jack. The driver you are using seems to have been written for a Gateway computer.

Hm, my previuos post dissapeared. Strange...
Have installed Vista on a second partition - under Vista sound is cool.
Booting back to XP - and all came back. No basses, poor hats.
Senselless situation - Sound driver works okay only under Vista, but this OS has sound problems itself.
I've used XP audio driver for 1535, found lilnk on this forum.
Thx.
Hi - Further my PM, just spent a few bored moments on my 1535 with Intel /IDT audio running vista32
From Windows media player to headphone jack, IDT equaliser (which doesn't seeem to do much anyway) set to default, output easily felt/heard from 20Hz to 15K + (my hearing stops there !). Working so can't do an electronic freq response but response quite acceptable via 'everyday headphones (JVC HA FX-77)
Quality of Reproduction via the headphone jack is by no means pure with various harmonic distortion and digital processing products quite evident in the output (Analogue swept sinewave). Lets be kind and call it MP3 quality. subjectively fine on 'pop' material
The internal speakers are ineffective below about 300Hz which is no surprise given their tiny size.

How did you get an XP driver for the 1535? If it is a driver for a different model that might cause the problem.
If you didn't wipe the Dell Diagnostics partition, use the audio test in that. It works without the driver so you can hear the unfiltered quality of the sound and determine if the problem is hardware or software.
