My last resort after hours of testing and re-installing different drivers. This is my story: I just updated my soundcard (x-fi xtreme music) to an Asus Essence ST, but it’s driving me crazy. I always used the ASIO setting in JRiver without problems, but the Essence ST keeps stuttering/glitching when playing music (mostly flac). The glitching/stuttering worsens when I browse (Chrome worse thand IE) or startup other programs. Other settings like WASAPI (with or without Event), DirectSound or Kernel Streaming give no problems, but in my opinion the sound quality is not good enough compared to ASIO (on my high end hifi rig). This is my HTPC setup:
Asus P5K Deluxe (latest bios) with 4gb ddr
Intel C2D 6600
Crucial M4 SSD
Samsung F1
XFX Radeon HD7770 video
Seasonic G series power supply
Asus Xonar Essence ST PCI
This is what I tried to fix the problem:
-Changing buffer settings (every setting possible). This makes no difference, a higher latency in the ASIO setting (50ms) only a little bit.
I used a latency checker to see whats happening and the signal is more restless than with WASAPI. I enabled the energy "high performance" setting,
disabled Intel Speedstep, changed priority to processes instead of programs, disabled onboard sound and wlan.
-Tried every driver possible, from the Unified drivers (low latency is the best option) to the latest or older Asus ones.
-Clean install Windows 8 and Windows 7
Who can help me out, I'm pretty desperate.....
