Ever since on night a few months ago, for NO apparent reason, my laptop speakers have been makign a fizzling/hissing sound on bootup.
1. This sound only occurs during the HP boot splash for Fast Startup and Normal Startup (incl. restart).
2. This sound MAY HAVE SOMETHING TO DO WITH BIOS because it is continuous when I am in the BIOS menu.
3. This sound does not occur when I have headphones plugged in, and NOTE it does not play through the headphones either.
4. Muting/unmuting and various volume settings do not affect this sound.
5. I have already reinstalled/updated both the BIOS and all the sound drivers, to no avail.
6. Thank you for whoever helps me to successfully fix this.
7. It is annoying.
