What is a simple, foolproof configuration for sound playing on speakers, a simple jukebox or playlist-player, a volume control onscreen, and input through the microphone jack?
I currently have sound but no onscreen control. I did get YouTube to record sound; not sure how it is working now though. Re-configuring sound has become a second life.
Do I want to use Jack? Pulse? ALSA? Something else?
I am running 12.04, with Gnome menu instead of Unity, on a Dell Optiplex GX-280, using the built-in sound.
Update June 2013: after recent Update Manager updates, the sound control applet re-appeared in the top menu line. The "PulseAudio Volume Control" is in the menus, I can turn up and down all apps separately there. I also can kill my sound by testing out different settings - turns out a wrong move also zeroes out the level on an app. I haven't installed, built, or edited a .conf lately, and it works! ALSA, and Pulse, are running, and not Jack .
