Looks like your motherboard does not support it. Newest sound driver for your board is 6.0.1.7701, and it does not include Sonic Studio. On the other hand, look at Maximus VIII support page, it has sound drivers version 6.0.1.7904 that does include Sonic Studio and Sonic Radar. So either it will not work, or you can try to download drivers from Maximus page (http://dlcdnet.asus.com/pub/ASUS/misc/audio/V7904_20160815_WHQL_DTS_StudioSound_SonicSuite_2228.zip?_ga=2.128194767.2131672601.1511718819-1021158752.1511718819) and try to install just the Sonic Studio, without sound drivers.
