Above configuration is generic one. Still it is possible to use different device for microphone and speaker, but you need to: 1. start terminal. 2. export environment variables sndio config. 3. start chromium from that terminal so it gets the env config. By default sndio uses rsnd/0 that is HDMI in/out for me. rsnd/1 is the build in microphone, rsnd/2 is the build-in laptop speakers, rsnd/3 is the USB Headset, rsnd/4 is the USB Audio Card (SoundBlaster). Usually setting `export AUDIODEVICE=3D"rsnd/3"` is fine as system default to have audio unput/output on usb headset. Sometimes I need to switch to built in microphone (`rsnd/2`) and external usb audio loudspeakers (`rsnd/4`) that can be done by exporting variables in dedicated terminal then starting chrome from that terminal. PulseAudio allows to switch input/output on the fly during application run when the meeting takes place this is why I prefer PulseAudio. Hope that helps :-) Tomek --=20 CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
