If you are using external speakers, do you leave your speakers at a certain volume, and change the volume on your computer, or do you leave the volume on your computer at a certain level, and turn the knob to change your volume?

I use my volume button on my keyboard ^^

Always use the knob on my speakers...I have a little wired remote for it. Much faster than going to the volume control on the taskbar. Plus there is a possibility of sound distortion if the volume is set to 100%...sometimes it's better to leave it closer to 90% and use the speaker knob.

Knob =]

i use the knob, after midnight i use my headphones, i have easily annoyed neighbors.

On a more serious note, I use the knob to set max desired level according to circumstances then I manage the computer audio level.

Usually the speaker remote, but sometimes the volume knob on the keyboard (which is tied to the windows volume control).

I have a volume control on my keyboard, so I use that.

On my tower I use the knobs. On my laptop I use the VC even though my headset has a little wheel too.

Gosh its not as simple as that :P

I adjust the volume on all my seperate programs for relative volume - I like music louder than movies for example

Other than that I try to keep the volume at my computer in the middle so that when I want to use my computer's remote I have the widest range of volume control
