PulseAudio Volume Control is a proxy go-between for the hardware and the underlying kernel sound component that provides device drivers for sound cards; ALSA (Advanced Linux Sound Architecture). PulseAudio was added to ensure compatibility with the widest array of hardware.
Pulse Audio Volume Control is easy use and pretty to look at. But, if something isn’t working right…
Open a Terminal [Ctrl]+[Alt]+[T] and type:alsamixer
Move to each sound control in AlsaMixer with the left and right arrow keys (the selected device will show in red letters). There are usually too many devices to show in one window; keep hitting the right arrow key the first time through to see them all. There are three different views: Playback [F3], Capture [F4] and All [F5]. Adjust volume with the up and down arrow keys. “00” means no volume, “MM” means mute. Toggle mute/unmute with the [M] key. Exit AlsaMixer and return to the command prompt by hitting the [Esc] key. Or, exit out of both by clicking the “X” in the top right corner, going to File > Close Window, or pressing [Shift]+[Ctrl]+[Q].
For more info about ALSA, see the AlsaProject homepage and the man page. PulseAudio Volume Control is free and open source software licensed under the GPL. PulseAudio is free and open source software licensed under the LGPL.
Gnash was the GNU Flash movie player and we’ve traditionally used the standalone version of it to play SWF files. Official Flash support from Adobe ended December 31, 2020 and Ubuntu removed Gnash from it’s repositories by the 20.04 release. But Remy van Elst resurrected Gnash as a Snap and worked with us to ensure our users can continue to use Gnash enjoy the 166 Christian games and videos we include.
Our Flash page has a bit more info about Flash and Gnash (and Remy van Elst). GNU Gnash was/is free and open source software licensed under the GPL.
