I cant play music.

When I try to play music through a variety of plug-ins, the console writes an error “BASS_StreamCreateURL error 2”
Sory for my bad English.

Umm what you trying to hear music from??? If it was like that one radio addon, reinstall it.

I tried play music with ULX, with Gramaphone in TARDIS mod and other thing. I tried reinstall gmod but its not help me.

Try this addon: http://www.facepunch.com/showthread.php?t=1159184

Error 2 says - can`t open file, but i shutdown firewall and antivirus, but not work.
