No sound after reboot on Debian Testing: a cautionary tale




So I rebooted today and no sound card is set up. It was working as recently
as a couple of hours before. I had just done a full-upgrade.

Some results:

lspci -v | grep -A7 -i "audio"
00:14.2 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] SBx00 Azalia (Intel HDA) (rev 40)
	Subsystem: Gigabyte Technology Co., Ltd SBx00 Azalia (Intel HDA)
	Flags: bus master, slow devsel, latency 32, IRQ 7, NUMA node 0
	Memory at fdff4000 (64-bit, non-prefetchable) [size=16K]
	Capabilities: [50] Power Management version 2
	Kernel modules: snd_hda_intel

00:14.3 ISA bridge: Advanced Micro Devices, Inc. [AMD/ATI] SB7x0/SB8x0/SB9x0 LPC host controller (rev 40)

01:00.1 Audio device: NVIDIA Corporation Device 0fbc (rev a1)
	Subsystem: Gigabyte Technology Co., Ltd Device 3642
	Flags: bus master, fast devsel, latency 0, IRQ 11, NUMA node 0
	Memory at fcffc000 (32-bit, non-prefetchable) [size=16K]
	Capabilities: [60] Power Management version 3
	Capabilities: [68] MSI: Enable- Count=1/1 Maskable- 64bit+
	Capabilities: [78] Express Endpoint, MSI 00
	Kernel modules: snd_hda_intel

(I was using the AMD audio.)

aplay -l
aplay: device_list:270: no soundcards found...

I happen to be a fairly experienced Debian guy, so I tried 

	modprobe snd_hda_intel

Lo and behold, sound was back.

So why did this particular reboot result in that module not auto-loading?
Should I submit a bug?
