Hello,

I have two computers that I want to share a set of speakers. I currently have the output of one soundcard run into the mic-in of the other soundcard, which works okay. The problem is that only the left channel of audio from the first computer comes through the speakers (I assume because the mic is a mono input). This is pretty irritating when listening to certain songs that have different parts split into different channels. Is there a way to make alsa mix stereo sound into mono and output it on the left channel? I have poked around with everything marked mono in AlsaMixer, but nothing seems to work. Any ideas?

Thanks!

I had a similar situation, except I had 2 sets of speakers and one source. I had to get a switcher; you might need a similar setup. They are pretty cheap at radioshack.
