Ubuntu-12.04: Sound not detected of ASUS K8U-X motherboard

Problem

Ubuntu-12.04 is unable to detect the onboard sound of my ASUS K8U-X motherboard. Within dmesg are these error messages:

snd_intel8x0 0000:00:04.0: PCI INT A -> GSI 18 (level, low) -> IRQ 18
AC'97 0 does not respond - RESET
snd_intel8x0 0000:00:04.0: PCI INT A disabled
snd_intel8x0: probe of 0000:00:04.0 failed with error -13

Environment

• Ubuntu-12.04
• Motherboard ASUS K8U-X

Solution

After doing the replacement underneath:

and after a reboot, the sound is working. Now dmesg reports all right:

Changing:

options snd-intel8x0m index=-2

To:

options snd-intel8x0m index=-2 buggy_semaphore=1

Doesn't help.

Removing the "m" - according to this website - does help!
