should i disable the PCI card's driver before rebooting, or is there any merit to having the driver fail to find the card (e.g., would it force it to load some default values)?

That shouldn't matter, since the driver should unload itself when the card isn't present. With Windows, you never know though. This is up to you.

so i started using that LCD monitor with the built-in speakers, and both picture and sound were working nicely.  but i noticed that if i had the monitor go into low-power mode with Windows power management or in response to the computer hibernating or suspending (but not physically turning off the monitor), there'd be a noticable hiss coming from the monitor's speakers.  i was gonna disable the low-power mode and tell family members to always turn off the thing, but i didn't do so soon enough. :'(  now today, the volume is greatly reduced, after somebody was away from the computer for a few hours.  i figured it was the speakers worn down by the extended hissing, but if i plug headphones into the same soundcard, i get the same diminished volume.

this suggests that the sound card itself got ruined..  but is such a thing even possible?  O_o  i would've thought the link between computer and speakers was more unidirectional.  the monitor speakers screwing the soundcard seems like the proverbial tail wagging the dog.  does anybody more familiar with computers and electronics know if this is a possible explanation?

also, is there some other volume control under Windows XP that i'm missing?  it'd be nice if there was a software cause for this.

thanks, and apologies again for the thread hijack.

It sounds like there is a sound card issue. Noise in the line tends to be related, so you probably should try to reseat the card and see if that helps.

You should be fine. Sometimes it is better to uninstall and then reinstall the drivers.

What sound card is this anyways? Hopefully it's not a Creative one...

There shouldn't be any issues (it's kinda like having USB devices), but registry entries tend to linger if you're not using it ever more.

the PCI card is a Crystal CS4281, Crystal being a Cirrus Logic product.  the onboard sound is Analog Devices ADI 198x Integrated Audio.  what's wrong with Creative, and what brand(s) do you recommend?

EDIT: ok, Crystal is the chipset, but the actual card is a Pine PT-2620-4.

i tried Lenophis' suggestion, and it's not acting any different.  still, it was helpful because when i had the card out, i saw what look like burn marks around Capacitor 81.  :sad:  that's probably the victim.  it's a little thing, and surface mounted (no soldering on back of board), so i lack the equipment and skills to replace it.

maybe if i get really bored and inspired one day, i'll attempt doing so.

in the meanwhile, i'll use the onboard audio, and never plug this monitor's audio cable into anything again.  :angry:

Well, if you like the bloated software, then go ahead. I've lost respect for Creative's subpar products anyways... the cheap stuff is definitely not good.

I would personally recommend the ASUS Xonar DX though...

It's dead Jim! I doubt it's the monitor... some things are meant to die if it's crappy hardware (or bad luck)...

i dunno.. you should've heard this thing hiss.  it was pretty noticeable.  besides, merely throwing the monitor into low-power mode was enough to cause the noise; it's not like i had to put the computer itself (and thus the sound card) into low-power.  one way to verify the monitor's the culprit would be to plug it into another sound card and roll the dice again, but that's not happening.

my other 2003 Dell has a Creative sound card (SB Live!).  it sounds fine and its drivers run fine, and i've never had occasion to use the supplemental software.  now, i've used very little sound on computers over my lifetime aside from playing MP3s on that machine, so i really have no basis for comparison as audio goes.  i could very well have a tin ear and not know it..  yet i still make a point to download 320 kbps MP3s. :P

another PC related question:

i have an old laptop.  on the AC adapter, the output is listed as 24V and 2.3A.  on the bottom of the computer, it says 24V and 2.2A.  so far so good.  yet on the battery pack, it says 14.4V (and 2.4 mAH for my initial battery pack, 2.2 mAH for the replacement; dunno what their actual current is).  how the hell does the thing run on only 60% of the voltage?!  i know that when the AC adapter is unplugged, the computer runs in a lower-power mode by default, but that can be overridden by putting it into "Turbo mode".  is there some device in the computer that cranks up the voltage provided by the battery pack to 24V?  like a transformer?

I'm not sure what you're asking for, except that you cannot make the battery consume more power unless you really want to deplete it ASAP. You can set the computer to max performance in Windows to effectively drain the battery faster.

The battery consumes as much energy as needed when the AC is unplugged... and recharges at a different rate depending whether the laptop is on or not.

The battery doesn't change really.. the power demand on the laptop can only change the battery consumption. Speedstep/PowerNow/CoolNQuiet is disabled by the power profile of the system through Windows or whatever OS you run (via the ACPI BIOS think).

no, i'm just trying to figure out how a computer that takes 24V can run off of a battery that only provides 14.4V.  that's a large discrepancy.
