my sound was working perfectly fine while suddenly it stopped after an update... I tried reinstalling alsamixer and stuff - did not work. When I start alsamixer, here is what i get:
Also in the upper right corner, when the sound menu is opened, the slider is inactive, same for the options in the Settings. Here is what I get with:
$ lspci | grep -i
audio00:03.0 Audio device: Intel Corporation Device 0a0c (rev 0b)
00:1b.0 Audio device: Intel Corporation Lynx Point-LP HD Audio Controller (rev 04)
Here is another:
cat /proc/asound/cards
0 [MID ]: HDA-Intel - HDA Intel MID
HDA Intel MID at 0xf2610000 irq 62
1 [PCH ]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0xf2614000 irq 63
Ideas?
