Sound problems, volume spikes to 100% at random

[oscarivera9]

Hi,
I'm using Ubuntu 14.04.1LTS and I've been having annoying problems with my sound. At random while listening to music or watching a video the volume will spike up to 100% briefly (for about a second or so) and then drop back down to where it was previously. The way I'm dealing with it is to have the volume ALWAYS at 100% and controlling the volume with my external speakers, but that's not a solution but merely a workaround. If using headphones that don't have volume control, there's nothing I can do about it.
Here's the output of aplay -l

i have the same problem, and yes, the only workaround is to set volume to 100% and control it from the speaker
