If I open PulseAudioManger on host "jim", I can seet that I have a "source" which is identified as "tunnel.asterisk.local.sphinx_record.monitor". I want my application to attach to this "source", however, my application can only use ALSA. As such, I assumed I need to use the pulseaudio alsa plugin. What do I need to put into my .asoundrc file in order to address "tunnel.asterisk.local.sphinx_record.monitor"? Name: tunnel.asterisk.local.sphinx_record.monitor Description: Monitor Source of Sphinx Recording Source on pulse at asterisk Driver: module-tunnel.c Sample Specification: s16le 2ch 48000Hz Channel Map: front-left,front-right Owner Module: 27 Mute: no Volume: 0: 100% 1: 100% 0: 0.00 dB 1: 0.00 dB balance 0.00 Base Volume: 100% 0.00 dB Monitor of Sink: tunnel.asterisk.local.sphinx_record Latency: 0 usec, configured 0 usec Flags: DECIBEL_VOLUME LATENCY Properties: device.description = "Monitor Source of Sphinx Recording Source on pulse at asterisk" device.class = "monitor" device.icon_name = "audio-input-microphone" Thanks, Jim
