Running 5.1 via AMD HDMI - what am I losing?

post #1 of 4
Thread Starter 
Question -
I've put together a budget build HTPC / gaming PC for the living room, and for convenience I'm running the sound from the HDMI out on my AMD R9 380 in to my Pioneer receiver's HDMI input (the receiver is feeding several signal sources, so this is just for convenience).

My question is, am I losing anything in the way of audio fidelity by using the AMD HDMI drivers? The mobo only has standard RCA outs (no optical) and is a generic realtek processor (not sure which exact chipset). I'm not against purchasing a PCI-e dedicated audio card (Creative / Asus) and using the optical outputs, but is there any point? I'm not an audio purist, I just want decent sound (which I think I am achieving in the current setup), but would the expeirence be improved by going with a dedicated audio card?

My setup is 5.1. if that makes any difference.

Any thoughts? Thanks!

No.

Still digital, thus the DACs on the receiver are still the limiting factor.

No and no.

OK! Thanks!

These days, HDMI is the best option for reliable and true surround sound. If the receiver supports it you could even set the output format to 96KHz 24bit and no standard consumer device will beat it in quality (besides subtle SNR differences that most receivers are good at anyway).

Only downside is if you want a system-wide EQ or other effects, which from what I understand is already present in many receivers...?
