Sending and receiving Sounds in MIRC:
WARNING!!! some sounds are very loud, make it a habit of checking your volume level when MIRC'ing

Setup:
1) In MIRC click on file, options, sounds, sound requests
   Check all boxes here except "Ignore if a sound is currently playing"
   Be sure that the Wave (*.wav) sound folder is set to your /mirc/sounds folder

2) Move down to DCC and click on "Auto-get file and minimize".
   Warning, make sure you have a good virus scanner and that it's up to date
   This setting is optional, you may wish to leave it off now, and only switch it on
     when a lot of sounds that you don't have are being played.

3) Move down to DCC, Folders, change "DCC Ignore" to "Disabled" and uncheck "turn back on in:"
   Click on the "*.wav,*.mid,*.mp3" item in the "DCC Get folders" pulldown
     If this option doesn't exist, add it.
   Click on the Edit button, and then on the In This Folder button and aim it at your /mirc/sounds folder

4) Click OK to save these settings.

5) Back in the main MIRC window, click on Tools, Remote
   Paste the following into the "remote" window (cut and paste to avoid typos):
                  on 1:NOSOUND:/msg $nick ! $+ $nick $filename
                  on 1:FILERCVD:*.mid,*.wav,*.rmi:/splay $filename
   Still in this window, click on Listen and make sure there's a check next to "Events"
5) Click OK to save these settings.

6) Exit MIRC and restart.

Usage, when someone plays a sound in channel, or in private chat, MIRC will automatically request
the sound file if you do not already have it, and play after it is received.

The request (!nick file.wav) will be done in a pm message to the user playing the file to keep from
clogging the channel. Don't worry, people playing sound files should be used to this, and if they are
setup like you are, they'll hardly notice requests.

If a long or annoying sound is playing, type   /splay stop   and the sound will stop playing in MIRC
If you just want to play a sound so only you can hear it, type   /splay file.wav
If you want to play a sound to the channel you are currently in type    /sound file.wav message
  the message part is optional
For more info, consult MIRC help on these commands.

Drag and drop.
Optionally, you can drag and drop .wav files onto the channel of choice, or to play to just one person, onto
their nick in the nicklist. You should only do this from your sounds folder since MIRC may not be able
to dcc send a file from a different folder to those requesting it from you.

To quickly enable and disable sounds, just click on file, options, sounds, requests and check or uncheck
the top box.

You've been warned twice :)
