i have a sound problem that has me stumped. i rebuilt a machine for friends,
installed their copy of xp home and secured it using standard best
practices: changed owner name and assigned password, disabled unneeded
services, installed antivirus software, installed pest patrol, installed
zone alarm, removed everyone group from all user rights assignments, set
local security policies (such as clear virtual memory pagefile, etc.).
however, all of this was done without attached speakers, so, almost
immediately after releasing the machine to the users, they began complaining
that there was no sound coming out of the speakers.
so, i had them bring the machine back in - and there was, indeed no sound.
the problem is that there should be, as the volume is not muted, the sound
device (built-into mobo) is installed properly, enabled - both in bios and
in windows - reports no conflicts, "use features on this device" is checked,
the "windows audio" service is running, using powered speakers that work on
other machines, logged on as computer administrator (owner). i have also
tried a known-good sound card in the machine, which also does not work.
alas, i am stumped - i am assuming the problem is with windows, since i
tried a known-good sound card attached to known-good speakers and they do
not work.
i have reinstalled/updated the sound card drivers, updated the system bios
to the latest version, disabled/enabled the sound devices, etc. also, there
is a tv-tuner card installed, but uninstalling it did not help the sound
issue.
i guess its possible that the problem is being caused by one of the security
procedures, but i have configured dozens of other machines in the same
manner and their sound works fine. i have also done extensive searches on
the web, including the ms kb and google, but have found no articles that
either apply to, or have resolve this issue. has anyone encountered this
problem before? did you find a solution? are there registry entries that
could be either corrupt or missing?
i would appreciate any help anyone can offer,
