Only other third party apps I have running, besides the trainer, is:
wireless network connection
local area connection (disabled)
connected usb device
sound and audio devices
synaptics pointing device (disabled)
btw worth noting, i've been able to use many other CHEATHAPPENS trainers in the past without any audio problems of any kind.
