Beeps are generated by a dedicated tone generator (pcppi(4) driver on PCs) connected to a small buzzer; it's not related to sound cards. On some machines, to save space, the tone generator and the sound card output are wired to the same speaker; there may or may not be a knob to control its volume. To disable beeps, it's simple: configure software to not use beeps. AFAICS only wscons and Xorg are using it; so you could disable it with wconsctl and xset respectively. let me know if this works
