I'm running Ubuntu 12.04 (LTS) on my Lenovo ThinkPad Edge E525 and I can't seem to get any sound out of the built-in speakers on my Notebook. I have tried rebooting, purging alsa, reinstalling and more and can't seem to get the thing to work. The same thing has happened on LinuxMint 16.

When I do "cat /proc/asound/cards" I get the following output

graham@graham-laptop:~$ cat /proc/asound/cards
 0 [Generic        ]: HDA-Intel - HD-Audio Generic
                      HD-Audio Generic at 0xf0b44000 irq 47
 1 [Generic_1      ]: HDA-Intel - HD-Audio Generic
                      HD-Audio Generic at 0xf0b40000 irq 16
 4 [ThinkPadEC     ]: ThinkPad EC - ThinkPad Console Audio Control
                      ThinkPad Console Audio Control at EC reg 0x30, fw unknown

Sound works perfectly fine, though if I plug in headphones into the jack socket. Can anybody help?

I have the same issue as well, running Netrunner (13:06 64bit Ubuntu). I can get some sound most of the time but not all of the time. Keeps prompting me to change sound cards when I hook up HDMI cables to it or on boot up with no external monitors and wants me to "remove" some of the drivers that aren't functioning. cat /proc/asound/cards 0 [Generic ]: HDA-Intel - HD-Audio Generic HD-Audio Generic at 0xf0b44000 irq 48 1 [Generic_1 ]: HDA-Intel - HD-Audio Generic HD-Audio Generic at 0xf0b40000 irq 16 29 [ThinkPadEC ]: ThinkPad EC - ThinkPad Console Audio Control ThinkPad Console Audio Control a –  morleman Apr 29 at 17:00
