There are at least 3 ways to make a system inaudible, because all the
volume controls are in "series".
Assuming the speakers themselves work ok, try
cat /dev/urandom >/dev/dsp
which ought to make a very loud noise.
A more gentle version is to use the program "speaker-test".
After this, check:
- the BIOS/hardware volume controls (the physical buttons)
- the state of ALSA (alsamixergui)
- the state of pulseaudio (pavucontrol)
- the in app volume control (eg VLC).
- the file you are playing.
HTH,
