I have my sound blaster z for around 1,5 years. It always worked perfectly fine, but now suddenly nothing happens when I switch from speakers to headphones in the sound blaster software. When I want to change it from speakers to headphones, the switch goes to headphones but the sound keeps coming from the speakers. When I plugin the headphones into the speaker jack and the speakers into the headphone jack, the sound will only come from the headphones even if I press the switch in the software. Is it a faulty product or is something else going on?
