For some reason, my sound doesn't work on my new machine with its present jessie install. It worked on my old machine(which had jessie) and it works fine here on Windoze(I use youtube to play old Bernie Sanders' speeches, or Mozart<g>). So what do I have to do? I can't find alsa to install, and pulsesudio is already installed. Any and all suggestions/fixes appreciated. Please spare the imprecations and chastisements! Alan
