If I remember correctly you need to be careful editting the class/team selection .res files because slight changes can cause tf2 to crash.

Unless your hitsound is corrupted and won't play (and is definitely a wave file) I have no idea why it is not working for you. Make one hundred percent sure that the file in sound/ui that you want as your hitsound is called hitsound.wav (where the .wav is the extension not part of the file name). Check to make sure your hitsounds are on (there is an option in advanced options for it). See if the console complains anytime you hit something. You only need to use

tf_dingalingaling "1" 
tf_dingaling_volume "1" 
tf_dingaling_pitchmindmg "150" 
tf_dingaling_pitchmaxdmg "1" 

for a hitsound to work btw.

The file that tf2 defaults to is in sound/ui called hitsound.wav. Just replace that file with your new hit sound (renaming the file to hitsound.wav) and it should work.

At both very high and very low dpi mice sensors tend to have problems tracking. Many mouse sensors tend to have decent performance ~1000 dpi, but each sensor is different. Some tend to work best with various multiples of some number (like 100, 150, 200, etc.) as well. To get a real answer you would be best off googling "{your mouse} sensor" or something similar to find forum posts by people who care way too much about mice. Hopefully from these sites you can find out the range your sensor works best at as well as any other non-ideal problems with your sensor such as mouse acceleration.

The general rule of thumb is pick a dpi that feels nice when you are on your OS (and not in game, since the OS sensitivity options suck for all OSs) and that should work just fine.

I was actually wondering the same thing very recently as well. I did some searching eventually landed on a natf2 thread http://natf2.com/topics/923-zoom-sens. The answer does seem to be setting zoom_sensitivity_ratio to 4.5 to get the same sensitivity zoomed in as unzoomed. I'm not quite sure why it is exactly 4.5, but it has something to do with the fov change on zoom.

How? At some point in the chain of computer to your ears you need to convert the digital signal to an analog one. Headphone jacks from a computer use either your sound card or your motherboard as the DAC, where as the USB headphones need to have a DAC built in. Every single USB headset I know of uses cheap components for the DAC for three reasons, 1) the headsets usually aren't of great quality so a good DAC is pointless, 2) a good DAC takes up a decent amount of space and 3) a good DAC requires a decent power supply to drive it. Now I am not sure if the headset DAC is better than a motherboard DAC, but it is definitely worse than an external DAC or a sound card.

Between an external DAC and a good sound card, I'm not really sure which is the better for gaming as opinions seem to vary. Personally, I believe a sound card produces better gaming sound than running the signal through an external DAC, but the external DAC is better for music. However, both are silly purchases for a normal user, i.e. a person with $100 or less headphones. Generally the order to buy audio equipment goes headphones->amplifier->DAC.
