Playback Ticking associated with NVIDIA Video Drivers SOLVED

FOR YOUR INFORMATION – Problem and Solution

Audacity 2.1.3 Executable Install, Build Date March 8, 2017

Problem: Video Driver conflict

  • HP Pavilion dv9000 Laptop with NVIDIA GeForce Go 7600 video hardware
    DUAL BOOT Windows 7 Professional 32-bit and Windows 10
    Creative Labs Sound Blaster Model SB0270 (Digital Music MP3+) USB I/O

With Windows 7 ticking increasingly audible the further you zoom into the waveform while in playback mode. Changed USB audio drivers from Windows version to the official version from Sound Blaster – problem persists. Same hardware (Dual Boot) on the Windows 10 (v7.15.11.7713, Date 12/3/2008) no audio playback ticking. Switched back to Windows 7 Professional on the same hardware there is ticking with the automatic NVIDIA driver (v, date 3/6/2009) installed by Microsoft. Ticking disappeared with the removal of the video driver and using the standard vga driver. It is also absent with the manually installed NVIDIA driver (v, date 1/25/2007) and (v, date 3/12/2007). These are earlier versions without monitor color correction features. The later versions include these features but cause ticking.

Downloaded drivers that work (correct display resolution, but no color correction) at:

I hope this information helps someone with older hardware.
