No audio device after reformatting

1410 not 1410T answering for.. this. non Tango PC."T"
"nothing is muted" THE SOUND ICON IS X RED BAR MUTED
OR ARE YOU SAYing I HEAR NOTHING AND SEEMS MUTED
BUT IS NOT MUTED, BECAUSE THE ICON IS NOT RED BARRED.????(sorry for caps... finger slipped, lazy to change)
if not muted turn up the volume first.

this is a laptop (way make folks look it uP?)
this PC has 2 internal speakers.
we next take dollar store ear buds or headsets, with 3.5mm phone plug on the end and test the line (speaker ) out jack
the jack on desktops is green on laptops its has logo of head sets.
if that is dead, too. we know the problem is the sound drivers dead.
NO OS stated but this PC is today 12 years old
and had XP new VISTA was released 3 years later in 2007
so what OS is there? click control panel, click system icon bingo?
99% of the time, sound dies for only 1 reasons
folks up grade the OS and find sound dead.
that is because, of software upgrades gone wrong.
the maker (we are not ACER at all here) is at Acer.com
not fixya.
The maker supports xp vista and w7 only on this PC.
so answer their 1 question, what OS click that
and get the sound driver rand load it.

Check that you have the proper drivers installed. The device may not be compatible for window's 7,in that case, get a pcmia wireless card that is compatible.

You can download drivers from the compaq support site.
An alternate solution is to use a driver update program to find and install missing or outdated device drivers.
