Rebooting today I noticed I have lost my sound device overnight:
$ sudo aplay -l
aplay: device_list:268: no soundcards found...
$ lspci -v | grep -A7 -i audio
00:1b.0 Audio device: Intel Corporation 7 Series/C210 Series Chipset Family High Definition Audio Controller (rev 04)
Subsystem: Intel Corporation Device 7270
Flags: bus master, fast devsel, latency 0, IRQ 10
Memory at e0730000 (64-bit, non-prefetchable) [size=16K]
Capabilities: < access denied >
00:1c.0 PCI bridge: Intel Corporation 7 Series/C210 Series Chipset Family PCI Express Root Port 1 (rev c4) (prog-if 00 [Normal decode])
Flags: bus master, fast devsel, latency 0
No Kernel driver in use and Kernel modules. I'd reckon that is not good.
Thought I need to have kernal module snd-hda-intel running.
$ locate locate snd-hda-intel
/lib/modules/3.13.0-37-generic/updates/kernel/snd-hda-intel.ko
/var/lib/dkms/oem-audio-hda-daily/original_module/3.13.0-37-generic/amd64/snd-hda-intel.ko
Any tip how to sort this?
By the way, as you can probably see above, I have the PPA Ubuntu-audio-dev/alsa-daily enabled.
