I am not a Linux expert either. But I had to do this linking to get linrad
working through my other card. It appeared that alsa installed the built-in
card as the first , ie. card0 and the other as card1. You might change this
the dsp device is normally linked to dsp0, ie to card0. I do not remember
exactly, but maybe linux gives you the choice to several ( active) dsp's.
But I remember vaguely that linking linrad for read only to f.e. dsp0, it
automatically also chose for writing the dsp0 input as well. Then I took
away the link from dsp to dsp0 and replaced it with the link to dsp1. That
solved the matter.
Other linux programmes, like krecord ( is a very good programme to see if
the recording is working and on which level, before starting linrad) always
take dsp and if you want it to use the second soundcard the link has to be
Well there are linux commands to link and delink. I do not know those by
heart. I used one of those filemanagers which has the linking/delinking
facility built in. Not konqueror but one of the other. Forgot the name.
I currently have no linux running so I cannot check.
I am experimenting with the SDR1000, another soundcard radio system.
