Unfortunately the info we just found gets us nowhere. I have tested all the possible and impossible methods to send a sound to client and what I have found:
CS does not accept SVC_SOUND SVC_SOUNDFADE SVC_STOPSOUND SVC_SPAWNSTATICSOUND if they are sent through message_begin(), when I run one of these 4 it disconnects and gives the error.
However if I type in console the command cl_messages
I get something like this:

That means that there is another way that these sounds are transmited and we do not have access to it. swds.dll is the way to make this work, and I think that SV_Multicast is the function responsible for selecting the clients who receive the messages.
Edit: Also about the cvars that are changed we also have this messages in console:

It means that we have another way that these are transmited...
Edit2: Also SVC_DELTAPACKETENTITIES is sent through a different channel.
Edit3:
I have got some code from quake engine so you can see some info regarding sound transmition.
