I have a Dell Precision T5400 with dual quad core xenon processors running 16gb of ram with a Windows 7 operating system. I seem to always have trouble getting a decent sound system. I watch a lot of movies and play games and I want some decent sound. It seems that my right speaker never works and I have tried two sets of speakers. I am using a simple pair of speakers connected to the single audio jack on the back of the computer. I do have a good video card installed (Radeon R7 370, 2GB GDDR5). It seems this card has the ability to send quality audio through it but I don't know what type of speakers I would need or if that is the best option. I think I have 1 expansion slot left open but I am unsure which type it is. I will need to take the cover off and check but I wanted some advice first. Would I be better off trying to install an audio card if I have an open expansion slot and if so what kind and what kind of speakers to use with it; or would I do better using the sound output of my video cad and if so what type of speakers would I need (I thing the audio is sent out through the HDMI connector but not 100% sure without checking the specs.). Anyone that can help me get a good quality sound system configured with what I have please help advise me. I am so tired of this blazing fast computer with an awesome video card but crappy sound. Please help.
