ASIO with USB DAC?

post #1 of 12
Thread Starter 
Alright, I used ASIO settings in Jriver Jukebox (and Foobar previously) with my X-Fi to great results, music was crisper and clearer. However, I'm now using an external USB DAC (E-MU 0404 USB) and was wondering if there's any advanage to running ASIO, or if the USB's software bypasses Window's sound crap the same way ASIO does.

The USB device is compatible with ASIO(2) as well as WDM, MME, AC3 and DTS.
Now, whether or not it's an advantage to run ASIO with your X-Fi or this USB is all down to your PCI's and USB's audio fidelity, converters and if relevant, the I/O's.

ASIO bypasses the windows software, mixing kernels, and doesn't really make that big of a difference unless that bypass is aimed at a hifi sound device that can handle the information sent.

Therefor, you should check if you have the device plugged in to a USB 2.0 because if you have less than that the device will only playback and record at 16bit 44.1KHz and render it worse than the X-Fi in terms of fidelity.

I heard about this thing called ASIO4All that apparently lets non X-Fi soundcards use ASIO.

Not sure if it works with the 0404, never really read anything about it at all.


*EDIT*
lol... nvm I misread your post horribly. Stress FTL

It's certainly USB 2.0, I don't think I've encountered a 1.1 port in years. Good to hear that the 0404 is ASIO supported.

ASIO DID have an audible advantage with my X-Fi, I'll have to test and see if I can tell a difference with the 0404.

I've heard that the EMU 0404 is ASIO native, so after you install the Vista drivers in J River Jukebox, under ASIO the EMU 0404 should show up under ASIO devices. I'd run it from the X-Fi though (if you have the proper cable). Otherwise you won't get the gaming benefits from the X-Fi. If you run it off the X-Fi, then continue to use what you are using (should be "Creative ASIO").

That would be my recommendation, as well. (Running through the X-Fi digital out). USB can have it's problems (stuttering under high CPU load, problems with multiple devices on the same USB bus, etc).

Yes, the 0404 is fully ASIO compatible. ASIO is at it's core a low latency interface, developed primarily for recording. It's on almost every pro interface that's worth it's salt.

Hahaha, Namrac had to ask a question.

So, if you set the ASIO to run through the DAC, will that redirect all audio through the DAC? That is what I have gathered based on the comments about the X-Fi not being used properly.

Yea, that's what will happen if you attach the DAC directly, if you attach the DAC to the X-Fi, you'd want to set the ASIO output to the soundcard, although you'll probably have to map it to the digital out. I know how to do this if anybody is confused (took me a while to figure it out).

Alright, I'm actually at home with just my laptop for a couple weeks, so I don't have the X-Fi.

Also, where can I get the cable for the X-Fi's digital out? It may have come with it in the retail package, but that was lost long ago.

So is there like an Optical Audio to USB adapter or something? If he has a USB DAC, how would you plug it into the X-Fi?
