I'm running Kubuntu 12.04 on my lenovo y410 laptop, and recently my sound started coming from both headphones and speakers at the same time.

I compiled and installed the realtek driver and now the automute works but the headphone volume is very low, and in alsa mixer the headphone slider is disabled (it just says 00 and won't adjust). Adjusting the speaker slider makes the headphones louder but its back low again when I reboot.

Any fix for this as it was working perfectly a day before (also before I installed updates)? I also tried alsa force-reload, removing and reinstalling both alsa-base and pulseaudio with no fix. When pulse audio was removed, I saw way more sliders even in kmix but it says headphones and theres no slider.

I'm only 13 and I really need help with this as I really don't want to return to windows but if this problem isn't resolved I will return to windows.

You can try removing the .pulse folder and .pulse-cookie file from you home directory. And a very warm Welcome to Ask Ubuntu! It's always nice to see questions about your own Laptop (I've also this Y410) – Anwar Oct 10 '12 at 13:55
I tried that last night to no avail. And thank you. You also have a y410? Have you noticed any problems such as very low wifi range (on all os's) and a bad dvd drive? Just wondered – Benaiah Oct 10 '12 at 14:14
Though the comment will be off-topic, but i'm answering this; I heard about those problems in this specific Model, but haven't faced much. I haven't tested with wifi range though, but the DVD writer is not bad, honestly. I've written many DVD's with it – Anwar Oct 10 '12 at 14:17
It is off topic, but there seems to be few owners of this notebook and i experienced both problems myself (i quick-fixed both with temporary solutions) but im still having audio trouble and its going to force me back to windows – Benaiah Oct 10 '12 at 14:19
