2016.8.30 works charming on HP Quadro with M-Audio M-Track at least when one uses this as a DAW-computer exclusively. I am not sure if it fits to day-to-day usage as well. I see absolutely no reason to upgrade to 2017.4.9. "Just do not touch, if it works". Especially taking into account, that 2017.4.9 is the first release which has PulseAudio within.
