How can I execute command on round start? I want to execute snd_restart to mute music on round start because I play my music and pressing a key bind to mute is annoying. Music muting does not help.

EDIT: I already tried:
"snd_musicvolume" "0.000000"
bind End snd_restart (work but is annoying)

volume 0, put that in autoexec.cfg or just type it in console

That's all sound.
