Another thing to check is that your Master and PCM controls are both at
reasonable levels.   The volume control in the frontend only changes one of
them (PCM by default?)...  so if the Master volume is set too low, you
won't get much output even with the volume "cranked" in the frontend.   You
might have already done this, but I'd double check those settings and crank
them way up if necessary, as you should get better sound quality without
the softvol component in the audio path.

Are your external speakers amplified?
