running a HP z820 workstation, Buster Mate. onboard sound does not cut it. I need more volume, and 5.1 stereo would be great I have a couple free PCIe slots What sage advice can I get here? Internal vs USB Brand? budget is modest, I tell myself under $100 thanks, Peter == I did not do my homework and bought a Sound Blaster Audigy Fx for $40.I am getting ready to return it, I could not even get it to work on Windows 10!
