Hi guys I’m hoping someone can help me. The ports on my rear and front panel won’t recognise anything being plugged in, tried headphones and my creative speakers. The only way I can get any sound is using a hdmi cable into my monitor and using the monitor speakers that are in built. But I’ve tested the headphones and speakers on my phone and they both work, creative cable is a bit dodgy but I can make it work. I don’t know what to do. Help please.
