Is it the same card reader on the laptop and on the PC? Does it do the same if you load the sounds from the SSD or from a different SD card reader?
Did you try disabling the anti virus temporarily?
Did you try unplugging all USB peripherals and closing all other programs? (like an audio configuration program from the default sound device or unplugging the USB DAC even if it's not selected)
Does it work when playing the sounds with DSoundTool or DKit Manager?
Edit: Is there any 5.1 or surround feature on the laptop? If the audio device is set to 5.1 try stereo.
