Hi Sri, I don't think we've heard from you for a while. Keeping busy?
> This will allow you to listen to all the channels > simultaneously (cacophony in my opinion, but hey, I am not the one > listening!) It's not so much that I want to listen to multiple streams of music at once, it's more that I want to hear the various sound prompts from the computers whenever they happen, audio from videos like YouTube, and the background sound therapy I have on (special white-noise at low volume) while listening to music (I don't always use the same machine for playing music or video, and I have more desktop than laptops these days). I can do it now, but it means 3 sets of speakers crowding my desk, and then physically unplugging and plugging cables if I want to tune in my short-wave radio onto a decent set of speakers, and stuff like that. Thank you for the detailed description of how to build all this. I used to love doing this stuff when I was kid - but I honestly don't know if I would ever have the time or patience to build this now (aside from work, I'm also renovating a 100 year old house), so I respectfully express my gratitude Sri, but decline your generous offer. There must be something ready made from somebody that does something this simple? 4 or more small audio input jacks, with some measure of volume control for each, to produce one "mixed" level of audio output to one set of speakers. I appreciate your reply, and sorry if I haven't been more clear on what I was looking for. Thanks.
