I recently did a system recovery on my PC notebook. After it was done i was prompted to update my drivers. I updated my mouse, sound and graphics drivers then restarted my computer. Now my sound is muffled and very low. Nothing is muted and the volume is up to max. In my device manager settings there are 2 sound devices. One is Nvidia and the other IDT, are they combating each other and making my sound muffled?
