    Alright, so this problem has been annoying me for about a week now. It's begun to get on my nerves. I have my laptop set up to play music on my hi-fi through a USB audio interface. I hear crackle. The kind that you hear on vinyl. Let me describe my set up:

    I'm using foobar2000 to output sound to a USB audio interface (Creative Sound Blaster Digital Music SX) via ASIO. The sound card sends audio to my pre-amp over optical cable. The pre-amp then sends analog audio to the amp and so on.

    The media is all flac. It is stored on a NAS and is being access over a wifi connection. There is no crackle at all if I play a CD. The CD player is connected directly to my pre-amp.


    Things I've tried:

    ASIO: Crackle is still there. I have checked and double checked that foobar2000 is using ASIO for output.

    VLC/WMP/other software: No improvement.

    Storing and accessing the media locally: No improvement.

    Using MP3 instead: no improvement.

    Buffer entire file to RAM before playing: no improvement.

    Drivers: all latest versions.

    Changing cables: no improvement.

    Now, I know the problem is with my laptop, because If I use my brother's (or any other computer) laptop, the sound is perfectly smooth. The question is, how do I isolate and then fix it?

    Also, My laptop is quite old (2.5 years). Although changing it is on the cards, it is currently out of the question due to 'budgetary issues'. I can budget upto 200$ on any other hardware to fix this problem though.

    Thanks in advance.

    Just a shot in the dark...

    I've encountered Static and Crackles if anything besides Master and Wave are not muted in the Windows Volume Control Panel (specificly Mic).
