I removed my LCD with cable, because it was broken. I’m using a Inspiron n5050 with a HDMI or VGA connected at TV, but the BIOS beeps(8times) continuos for ever and ever. Note: on windows os when install idt (high definition audio codec) driver the beep was muted. There is a way to control the beep volume or mute it through Ubuntu Or Gub2?
