Is there a neat software solution for patching, say, the left channel of PCM output to both channels of the line output of my soundcard in ALSA? I need this because I've just installed a TV card, which works great except that the dual language function doesn't seem to be supported. So I get English in one speaker and Chinese in the other. I'd rather have the same in both. I thought of doing it with the JACK patchbay, but the TV output unfortunately doesn't show up in JACK. Thanks for any help, Peter C
