Bug Description

After unplugging external speakers, volume (loudness) of sound on laptop speakers is very low although it is set to 100%. This only happens if both, analog headphone and analog speakers ports are set to 100%. To get loudness back, I have to change master volume of analog speakers below 100%.

Hi Nikola!

Didn't we talk about this in another bug? Or was it with someone else, or on IRC? Anyway, I worked on a fix last week and hopefully it'll be deployed into Ubuntu this week. I hope you can help with testing verification once the SRU team asks you to. Thanks!
