I have a Sony VAIO notebook, type VPCZ13A7E running Ubuntu 12.10 64 bits. While using sound, I'm experiencing these symptoms:
- sound crackling when computer awakes
- Sound becomes jerky and switches between my earplugs and the integrated speakers. I can also see the sound indicator changing by its own, when this is happening.
How can I fix this? And, optionally, for my understanding, what are the origins of these problems?
