The K Desktop Environment

6.5. Why won't KBiff play my newmail.au file?

KBiff uses the KAudio class to play sounds when new mail arrives. Currently, this class only supports .wav files. If you wish to play an .au file when new mail arrives, try getting the SOX package and put 'play newmail.au' (or just 'cat newmail.au > /dev/audio') in the Run Command option.
