Comment 6 for bug 942102

quick and dirty workaround:

- write a short shell script that plays the sound using mplayer or similar
- have quassel execute that script using "Run Command" (for example on highlight)

Example:
$ cat bin/highlight.sh
#!/usr/bin/env bash
mplayer /usr/share/sounds/KDE-Im-Highlight-Msg.ogg

- Then in Quassel's highlight settings, check "Run command" and point it to your highlight.sh
