For the list archives.... I had things inside out and upside down for a while, but finally got things sorted. What I wanted was a virtual audio cable to pipe output from one app into a device that could be set as the input for another app. The answer was module-null-sink and here's how I have it plumbed. My platform is Ubuntu 11.10, though this is fairly generic. My ~/.asoundrc pcm.pulse { type pulse } ctl.pulse { type pulse } pcm.!default { type pulse } ctl.!default { type pulse } pcm.vac { type pulse device vac } pcm.vacmonitor { type pulse device vac.monitor } In /etc/pulse/default.pa I uncommented and edited one line load-module module-null-sink sink_name=vac The end results amixer -i Simple mixer control 'Master',0 Capabilities: pvolume pswitch pswitch-joined penum Playback channels: Front Left - Front Right Limits: Playback 0 - 65536 Mono: Front Left: Playback 22037 [34%] [on] Front Right: Playback 22037 [34%] [on] Simple mixer control 'Capture',0 Capabilities: cvolume cswitch cswitch-joined penum Capture channels: Front Left - Front Right Limits: Capture 0 - 65536 Front Left: Capture 19194 [29%] [on] Front Right: Capture 19194 [29%] [on] pactl list short sinks 0 vac module-null-sink.c s16le 2ch 44100Hz SUSPENDED 1 alsa_output.pci-0000_01_00.1.hdmi-stereo module-alsa-card.c s16le 2ch 44100Hz SUSPENDED 2 alsa_output.usb-Burr-Brown_from_TI_USB_Audio_CODEC-00-CODEC.analog-stereo module-alsa-card.c s16le 2ch 44100Hz SUSPENDED 3 alsa_output.pci-0000_00_14.2.analog-stereo module-alsa-card.c s16le 2ch 44100Hz RUNNING pactl list short sources 0 vac.monitor module-null-sink.c s16le 2ch 44100Hz SUSPENDED 1 alsa_output.pci-0000_01_00.1.hdmi-stereo.monitor module-alsa-card.c s16le 2ch 44100Hz SUSPENDED 2 alsa_output.usb-Burr-Brown_from_TI_USB_Audio_CODEC-00-CODEC.analog-stereo.monitor module-alsa-card.c s16le 2ch 44100Hz SUSPENDED 3 alsa_input.usb-Burr-Brown_from_TI_USB_Audio_CODEC-00-CODEC.analog-stereo module-alsa-card.c s16le 2ch 44100Hz SUSPENDED 4 alsa_input.usb-Microsoft_Microsoft___LifeCam_Cinema_TM_-02-CinemaTM.analog-mono module-alsa-card.c s16le 1ch 44100Hz SUSPENDED 5 alsa_output.pci-0000_00_14.2.analog-stereo.monitor module-alsa-card.c s16le 2ch 44100Hz IDLE 6 alsa_input.pci-0000_00_14.2.analog-stereo module-alsa-card.c s16le 2ch 44100Hz SUSPENDED So one app that is properly pulse aware now sees for capture and playback devices "vac" and "vacmonitor" My issue now is that the other app I wanted to chain into this does not seem to have sound implemented completely so it still isn't seeing it. However my "mystery" in the config is solved now :-). -- 73? ? ? de? ?? Chris? ? ??
