Speaker no audio (on anything played) except a buzzing sound

[Dyth]

I just bought a new PC (CYBERPOWER Empire Pro Gaming PC) everything working fine until I plug my speakers and all I can hear a buzzing noise, nothing else. I've checked all recommended method to fix it from 'Sound' Playback option to 'Device Manager' Sound, Video and Game Controllers restarts. but nothing working... Does anyone know how or what's causing this problem even??. Plz help!

Check whether the power supply for the speaker is the correct one or not also try connecting the power supply for the speaker system to a different wall outlet and if your using 3.5mm jack try connecting it to a different audio source like ipad or mobile and check the response. also let me know the exact make and model of the sound system and the type of cable used to connect the speaker to provide you with the correct solution

I understand where you coming from and I have tested it with 2 different type of sound system, even with 2 more headphones but they all have same annoying noise (both headphones and speaker system were tested into my laptop and works just fine) I've also plug it in different wall plug but nothing... This pc has a GA-78LMT S2P motherboard and a 5.1 Surround Sound ( not sure if this helps but I got my pc spec ).
