Hello.

In Portal 2 coop-mode, if you fall more than 3 blocks (3x128 units) you hear a falling sound.
Coop-Mode has a bug for the client (p-body), where the sound may stay loud all the time,
unless the player kills himself (or map is restarted). [lag/connection related topic]

screenshot of the console 'soundinfo':

It is always channel 64 and always the same sound.
"playerplayer_fall_whoosh_lp_01.wav"

Is there a way to stop this sound, when the host (atlas)
hits the trigger on the floor of the spawnroom?

I already tried 'stopsound' and 'snd_restart'.
Both of them work, but they also stop all other sounds like funnel, lasers, music.
