So you actually want to synthesize the beep? Is that right? If you really do want just a beep you could synthesize the sine wave yourself pretty easily. The one and only source code example in the libao coincidentally does exactly that. http://www.xiph.org/ao/doc/ao_example.c > Right now I use Nas, which has good support from Jon Trulson.

The libao alsa driver (alsa09), which I assume you would be using, allows you to specify which device (ie. sound card) you want to use. The oss driver will too. > E.g. if it is 11:30 I want to produce 5 beeps for maritime chimes. > If the dialup line goes down I want to produce 9 beeps. > > I would prefer to produce the beeps for a particular soundcard, for the > user that is logged on to a monotor that uses that card. A few lines of tweaking to that example I linked above should do exactly what you want. -- CJ van den Berg mailto:[EMAIL PROTECTED] xmpp:[EMAIL PROTECTED]
