Slightly off topic. Ok, you've got several computers at your desk. One primary Linux desktop, one not-linux notebook, maybe one more. And a CD player/radio. Maybe an MP3 or Minidisk player. Notebook has crappy speakers, but that's the one used for listening to internet radio, etc. Now, you could have 4 sets of powered speakers plus the CD player. Or you could find something to mix the 3 outputs together and run it to a single set of speakers. Or even use the AUX input on the CD player. But what could one use to do that? Only thing I've come up with is this: http://www.music123.com/Rolls-MX42-RCA-Stereo-Mini-Mixer-i138112.music and I'm not sure if that would work well with headset/speaker out level on multiple sound cards. It's just a set of jacks with 10K pots in them, so if each pot is cranked all the way up, there's basically no impedance between each sound card/device output. -- ============================================================================ Neal Rhodes MNOP Ltd (770) 972-5430 President 4737 Habersham Ridge fax: (770) 978-4741 Lilburn (atlanta) GA 30047
