Return to Castle Wolfenstein Sound Problem fix

Here is the sound solution for the RtCW sound problem (thanx to FonFon):

Replace the line "set normal "cl_freezedemo 0; timescale 1;echo ^2Normal; vstr normal2;"" with "set normal "cl_freezedemo 0; timescale 1; s_stop; echo ^2Normal; vstr normal2;"" in the Return to Castle Wolfenstein configs of Seismovision. This will also be in the next release of Seismovision.

The command "s_stop" resolves the sound problem.
