Richard.....
Audio Playback very low on mine.
As for speakers, in view of the limitations of the average internal ones in most notebooks, was just looking for a couple of small neat portable stereo ones for improved quality to listen to music now and then.
Hadn't given thought to connection yet (!) but in answer to your question:-
1xheadphone jack
1xmicrophone jack
1xS/PDIF Port, supporting 5.1 channel output for home theatre (but maybe relevant for this more limited requirement?).
.....& the usual array of USB's, Firewire etc.
