i finally got around to enabling 4ch mode on my motherboard sound card and attaching that extra pair of speakers for REAR left and REAR right. mwahaha!! some utilities I needed include: alsa-utils alsa-tools. this script was useful too. https://github.com/hello2himel/linux-audio-fix
I had just fixed an old pair of Altec Lansing ACS91 speakers and thought that I could use them as Rear speakers and what do you know, they actually sound really nice.
