segfault when reconnecting

So in general we just need to look over the self->priv->sound[MspType].play GstElement lifetime handling. It looks like some use-after-free case somewhere, where the element has gone away, but the pointer isn't properly updated or some such. Crash from just disconnecting after some MSP stuff on use-gio:
