I have X-Fi Elite Pro installed on my Windows 7 computer. All new 2015 PAX drivers installed and working but only for line out in full. Set up connects line out from card itself to small speaker system and coax from X-Fi console to Phillips sound bar and optical to Pioneer HT. I have five device subs in my player which are Creative ASIO, DirectSound, WASAPI, WASAPI Exclusive (Event) and WASAPI Exclusive (Push). Last four include 2 Creative devices each: Speakers (Creative SB X-Fi), SPDIF Out (Creative SB X-Fi). All schemes create perfect sound either through line out to Speakers or SPDIF. When it comes to Speakers - everything is OK. I can adjust volume with Creative console launcher and I am able to switch on or off any effect from launcher (such as CMSS-3D, crystalizer, EQ). When it comes to SPDIF either coax or optical no effects at output and I even cannot adjust volume (i.e. I am tuning knob on launcher but sound volume stays still). And this is actual for any sub. Any help appreciated and thanks in advance.
