OK, in my quest to get the output of one application to be used as the input for another, I got module-null-sink all set from list short sinks 9 vac module-null-sink.c s16le 2ch 44100Hz SUSPENDED from list short sources 12 vac.monitor module-null-sink.c s16le 2ch 44100Hz SUSPENDED My two applications recognize ALSA devices. One of them for example sees the following options for output devices Audio Output Devices: id: 0 -> hw:HDA ATI SB,0 id: 1 -> hw:HDA ATI SB,1 id: 2 -> hw:HD-Audio Generic,3 id: 4 -> hw:USB Audio CODEC,0 How do I now get ALSA to see the null sink and its monitor so the apps in turn can use them as an output and a capture device? I've Googled around and can't find an example so far. -- 73? ? ? de? ?? Chris? ? ??
