While playing a CD on my computer, I may interrupt the music by clicking on the start/pause button on the Windows Media Player. When restarting, a popping (explosive) sound may come out of the speakers. .......when I use it as an external DAC, bypassing the STX’s DAC, it never pops in the same pause/restart operation.
2. Low background sound (noise) when playing a CD via STX
This occurs in a section of the CD where no music is played, such as the very start of playing the CD, in a pause between movements, or at the end of music. The sound is significantly reduced or nearly eliminated when the music starts.
3. Volume control in the Xonar Audio CenterAt which level should it normally be set for playing a CD? At the moment, I set it about 40% so that the highest sound level is about 0 dB, and use the volume control of the amplifier for finer adjustments.
I am almost exclusively a classical music fan. I have nearly 200 CDs that I made by recording CBC FM broadcast in the past 10 years. I have a few commercially recorded CDs, most of which I do not like, as a quiet section is almost inaudible and a loud section makes me jump out of skin.
BTW, to my personal taste, the Yamaha DAC sounds more musical (very comfortable to listen to for a long period of time), as compared with STX that sounds, albeit crisper and more detailed, somewhat too bright...
Also, apologies for my English; it is not my native language.
Some additional information would be helpful:1. Please describe in detail the type of PC you are using and how it is connected to your audio system, e.g. Between what components and into which jacks? What kinds and lengths of cabling?2. Is the PC plugged into the same power circuit as the audio system?3. When you "play" a CD are you inserting the CD into your computer and playing audio from it or are you playing files previously ripped from the physical CD and stored on the PC hard drive?4. You mention better results using your Yamaha CD recorder as an external DAC; how is this wired up?5. Have you visited the ASUS website and updated to the current drivers?
