Comment 4 for bug 83015

Seeing that :
[ 14.860153] saa7134 ALSA driver for DMA sound loaded
[ 14.860187] saa7134[0]/alsa: saa7134[0] at 0xd8000000 irq 20 registered as card -2
[ 14.860675] saa7134[1]/alsa: saa7134[1] at 0xd8002000 irq 21 registered as card -1
[ 14.911163] cannot find the slot for index 0 (range 0-1)
[ 14.911169] hda-intel: Error creating card!
[ 14.911174] HDA Intel: probe of 0000:00:1b.0 failed with error -12

It could be :
-An alsa driver problem (not correctly detected card)
-A conflict with the saa7134 driver (I don't really understand those -2 and -1 card number)
-An ACPI problem (IRQ conflict)

I'd start by blacklisting saa7134 in /etc/modprobe.d/blacklist to see if there is any change.
