Realtek HD-audio manager Wont Start

Hi i am running windows 10 64 bit and i have been having a problem with the above, i have a headset and Mic plugged into the front jacks of my case and i have speakers plugged into the Mobo jacks, for some reason everything i listen to is very quiet even though volume is turned up full, if i click the play button in Realtek to test my headset it sounds fine, another problem i am having is Realtek wont boot with windows.

So you have the speakers turned up all the way and also volume control on the headset if there is one and also the slider bar for volume control up all the way? Did you install the windows 10 driver software for the sound card? Open task manager and click on startup tab to see if realtek is listed.

Hi it was not listed under startup, i uninstalled it and i also uninstalled Razer Synapse because i was using there virtual surround sound software i then reinstalled Realtek and it seems to of fixed it even though there are still Razer audio drivers in Device Manager that if i uninstall just get added back.

When you uninstalled razer via device manager, did you get the option to uninstall driver software as well? Usually you do.
