For me:
Simple mixer control 'Beep',0
  Capabilities: pvolume pvolume-joined pswitch pswitch-joined penum
  Playback channels: Mono
  Limits: Playback 0 - 15
  Mono: Playback 15 [100%] [0.00dB] [on]

Which comes from pcspkr.

Could  you please disable pcspkr and test the beep by controlling via the
mixer?
