Motherboard optical vs USB to SPDIF converter

post #1 of 5
Thread Starter 

So I'm at the point where I'm thinking about upgrading again. The USB input on my Decco took a crap and I do not want to pay them to fix it again. So I am going to switch over to optical or coax input. Is it worth it to get a USB->SPDIF converter or will the optical from my motherboard be good enough? Thanks.

 

EDIT: Maybe I will just go with a cheap PC sound card. I'd rather go through PCI than noisy USB.

Try the optical connection first, see how you like it, and see if the audio quality at least matches the USB connect, you use to have.

Sounds like you are cutting off your nose to spite your face.

 

It's not USB per se that's crap. Your product's implementation might be. If that's the case what makes you think any other part of your Peachtree Decco is any better?

 

Bite the bullet, accept you bought unwisely and start again. Never go back(wards).

Indeed.  Do not throw good money after bad.

 

And "noisy" USB?  If the device is USB-powered, it's a ground loop.  If it's powered separately, then you've a bad cable in the chain or heavy RF/EM interference.

USB deals strictly in digital streams--lots of 1s & 0s, not an analog waveform.  Mess up that digital bitstream, and you get very noticeable glitches, not noise.  It's very much like a satellite TV transmission:  When the signal is good, it works.  When the signal is interrupted even momentatily, you get blocky video & glitchy audio.

 

Personally, I prefer USB over optical & coax.  With a USB connection, you get the shortest path and least processing to get out of the system (CPU > southbridge > USB), whereas the on-board audio tacks on the internal audio codec, and an add-on card adds the PCI(e) bus and it's codec before leaving the system.

As far as cables are concerned, I just used the 1m USB cables that Dell ships with their monitors--they just happen to have a choke at one end to combat interference.

Maybe I wasn't clear, the USB input stopped working.I need to decide whether to just run optical or run optical through a USB converter from the pc.
