In Windows XP I've found a choice for "in" and "out" between "USB Audio Codec" and 3Port USB Audio Codec" but each time I select "USB Audio Codec" it keeps saving "Port USB Audio CODEC" and it does not trigger the transmission, it does not seem to workI don't know the signalink... but if it is an external sound card the mixer
should be called CODEC.
The Port CODEC[hw:1] is the port audio driver, it is the same soundcard as the CODEC
If you normally use Pulseaudio that should work also.
With Ubuntu 10.04LTS I've finally chosen for "in" and "out" "CODEC[plughw:1,0]" as I do not find a "pulseaudio" choice and it works here after I've selected for my Audio Codec : 1 output/1 input and Analog Stereo Dupleix.I use Pulseaudio on my new Lubuntu machine with the internal soundcard running 2.0.12.But then you need to configure Pulseaudio correctly by using the pavucontrol program(sudo apt-get install pavucontrol) to set hardware config and audio levels.You can use that to set the external soundcard as default (switch of the internal one).On Lubuntu both active mixers are called Pulsaudio.I have been able use a USB headset as a sound card, so I know it is possible.But it will take some trouble to find the right combination.The mixer config is stored when you quit the program, you may have to restart the appa few times, but as soon as it works it will be stable.
Thanks again for your help, 73, Jean-Claude - FK8IH
