Using audioctl and mixerctl I just experimented until I got settings that
workied, then put them in a file sourced upon logon.  Very simple hack.

I used:

audioctl play.gain=255
mixerctl record.volume.mute=off
mixerctl record.source=mic      (uses mic line input- mic2 uses laptop mic)

I am sure there are other things that could be tweeked as well, but the
levels needed for the program I/O are perfect.
