I experience the same problems like you.
This is my sound data:

I run KDE 4.10.4 with Kernel 3.10 now.
When booting and login my volume is muted. So I open KMixer and set volumes. Now I can hear the build-in speakers in events or in movie. Then I finish my work and shutdown my laptop (an Acer V3-571G).
When I boot then my laptop later, e.g. hours later or next day, then the sound is muted again. This is replicable.
And here some curious: When I connect an external headset to my standard audio while muted, then suddenly the muted sound changes to 'unmute' and I can hear sound in headphones then. I don't touch the settings when plugging in.
And 2nd: when I disconnect the headset then the volume is still 'unmuted', exactly, I can hear the sound from the build-in speakers then.
I hope, this is a hint for the experts here.
