The beeping at power‑on is not a Windows or audio issue; it is a hardware (firmware/BIOS) warning from the PC before Windows even loads. The provided information only covers sound problems that occur after Windows has started (for example, low volume, no sound, or poor audio quality), so it does not apply to loud beeps during power‑on.
