I thank u once again stanley.i have finally find it am relieved.am sendin you the method,in case someone will need it,am sure it will be of great use.
FOR WIN XP AUDIO & MODEM DRIVERS IN A840/A860, I RESOLVED MY ISSUE USING COMPAQ DRIVERS, (sp34386.exe, Conexant High Definition Audio Driver (for AMD) &
sp32646.exe, Microsoft Universal Audio Architecture (UAA) Bus Driver for High Definition Audio).
FIRST NEED TO INSTALL sp32646.exe, THEN sp34386.exe, AFTER THIS THE SYSTEM SHOULD RECOGNIZE AUDIO AND MODEM HWs, AFTER THAT USE DELL DRIVERS R192894.EXE & R190098.EXE, GOOGLE IT…
GOOD LUCK…
