I got myself a new seond hand mother board and have now no more sound.
First one MoBo was installed and there was no sound. So we changed to another MoBo and again there is no sound.
Giving command "aplay ./sound/alert.wav" output is:
Playing WAVE './sound/alert.wav' : Unsigned 8 bit, Rate 8000 Hz, Mono,
yet nothing can be heard.
I tested my speakers they are working properly. At computer shop where
Mobo is installed there is no sound well.
I booted in to Knoppix live there again is no sound.
Here are some specs:

On both MoBos the sound card was detected. We even put an external
sound card which was as well detected, yet no sound and no errors.
What could be the mystery?
