Noisy rear shock

[clemsta]

Noticed over the last couple of days when jumping on the bike that i hear a hissing noise, when i sit on the bike i hear air being pushed out and then it sucks air in when i let the weight off the rear end. It sounds like its coming from the shock but i can't see any leaking oil coming from it. sounds like air is escaping from the bottom of the shock (nearest the wheel)
Any ideas

fixed it!

i took the seat off to have a better look and found that the noise had gone, the sponge in the seat was wet and thats what was making the noise, feel a bit stupid now. Got home today to find that my left fork seal has started leaking, so i've got that to do now.

thanks
