Dear gf, thanks for your response. As far as I can assess that, implementing the workaround did not have noticeable impact on the system's battery run time.

This problem already existed when it ran 15.10. Regardless if the notebook is connected to AC or not, external speakers are connected or not, the audio output seems put to sleep somehow after ~6 seconds. Whenever a process tries to output audio, it needs approx. 4 seconds for the audio to actually come out. Despite this laggy behaviour, it is really annoying because most applications freeze during this time. Besides different apps of daily working are affected by this (Thunderbird, MPlayer, VLC, ...), this even applies to the "volume changing sound" when using the volume -/+ keys. In detail this means: if I press the volume "-" key multiple times, the volume overlay freezes for approx. 4 seconds and then all requested volume change sounds are played altogether.
