don't ask me why, but ALSA sometimes sets everything up muted
The logic is that someone might have headphones on or a loudspeaker turned up high and get deafened when/if sound came on unexpectedly loudly during an intall, so it is safe to leave people to turn the sound on knowingly. Don't shoot the messenger. ;-)
Sometimes unmuting in KMixer is enough.
The easiest way to sort it is with pavucontrol, but that means installing pulesaudio. <dons flameproof suti> ;-)
