I've 8i6 and I use it with Ubuntu 14.10.
Sometimes I've experienced a similar issue (I don't know if it is your
case or not). I've checked all the volumes with alsa mixer, and I've
found that sometimes some buses (which are used for monitor out or main
out) are low in volume or even mute or misrouted (i.e. not "connected"
to monitor out).
Unfortunately, the alsa mixer interface are not the best way to change
those parameters, because the 8i6 has so many channel and buses that
alsa mixer becomes confusing to use!
