Me and my friends also hear these sounds, from opening a soda can, reloading, zombies, footsteps,..

Also this problem:

I have a SIMILAR problem also, it began with me getting extreme desync 100000 or something, then all of a sudden this started happening, I log on to new servers can SOMETIMES see for a few seconds what's around me (my friend(s) etc.) and then massive lag (my friend running on the spot when he's actually next to me (talking over TS) sometimes I can't see him at all. I have 0 ping ,0 bandwidth, 0 desync all the time and so does everyone else on the server.

my friend says when I push my hotkeys (1, 2, 3, etc.) that he can see me equipping the item but then automatically putting them away again, this started today around 11:00AM (UTC+10:00) and has continued until now when I just tried to log on to multiple servers for over an hour to see if I could play.

Ok, then I want to be able to respawn my character the moment I get infected or the moment when i'm bleeding ooh and not to forget the moment when my shoes get wet, because it's damn hard to run around with wet shoes and if i'm in a forest it takes ages till i get to a town and find some dry shoes to wear :(

but seriously, a broken leg is NO reason for respawning.
Rip you shirt, get some sticks combine it and splint your leg, or get some morphine from a hospital. You can also opt to not eat and starve, crawl to a zombie and let him knock you down, go to first person and shoot yourself in the leg till you bleed, Eat rotten fruit and die, Jump off a cliff
OR
Get some friends to help you out in the game (I heared it's fun playing with friends ;). )

1. Crawl and look for help.
2. Wait for starvation.
3. Go outside your house, get back to the real life. Come back after an hour and you are able to respawn.

You should not be able to respawn with a broken leg, it's a survival game. If you can respawn no matter what happens to you the game will get boring and everyone will start respawning the moment they get hungry or thurst.
