No problems here anymore. ASIO works great with Juli@ now. I didn't even remember I had this problem.

I don't know how to use the ASIO that comes with the XFi. It pops up in some of the choice screens, but choosing it does not lead anywhere. They tout the ASIO for the recording ability more than how we like to use direct streaming to bypass their system to an external DAC.

If anyone can give me some instruction into the use of the Creative ASIO instead of ASIO4All with Foobar2K, I would be happy to try it, and learn some more.

As a newbie in the headfi world, I consider myself still pretty tonedeaf, but I do like all the new learning and experimentation this hobby has brought.

So, ASIO music doesn't stop for you when windows plays other songs? How did get it to do that?

I've been having problems getting KS to work at 192000khz (ripped DVD-Audio tracks) on my chaintech av-710. Is this a limitation of the card, Kernel Streaming, or something else? Is it the case with AISO? Any info is appreciated.

Your card doesn't support that resolution. 96khz is the max.

I know other people hear it, too, b/c Bert Doppenberg (or the Oris hornspeaker fame) recommends using KS instead of ASIO b/c KS is more (paraphrase) "natural" sounding to him. He obviously uses SET/oris horn speaker system, not headphones.

I hear this difference, too, but for the same reasons I prefer ASIO. To my ears, KS is a bit more liquid, laid-back, and has slightly softer sounding leading edges, leading to the "natural" sound.

ASIO to me has crisper leading edges, more forwardness and clarity, and better bass definition. ASIO is less forgiving of bad recordings, which will sound less "natural" and more digital. However, on good recordings, I believe ASIO to have better resolution and fidelity.

Before someone posts the usual "ASIO and KS should sound the same" statement, I highly recommend carefully comparing them using music you're intimately familiar with, preferably with revealing speaker systems.
Would this apply to ASIO via ASIO4ALL too? I think I'm hearing something similar to what you've described with my own setup (with nothing nearly as impressive as a K1000), but its strictly "I think", the differences are so small it could be nothing but placebo.

Yes, ASIO doesn't stop.

We have different sources so I'm not sure how you should do it.

Juli@ supports ASIO by default so I just chose ASIO output from foobar with these settings:

Thread priority: Highest
Buffer size: 10
Shift output channels: 2 (I need optical out too)

In playback settings I've unchecked all the boxes and Output data format is 32bit fixed-point.

The Juli@ is an example of a card with a unified driver architecture.

There is a common driver that deals with mixing routing, sending and receiving bits over the PCI bus etc. and then ESI has implemented the glue code to have that driver expose itself to MME, WDM, ASIO, and GSIF.

In fact within the driver you can clone and route audio streams between these different APIs by a simple UI tool.

You can also call all these sound APIs from different applications in parallel and the driver will perform mixing when necessary. Mind you this is bit perfect if you only play one stream.

When I had xfi, I used asio(dll) found here
and it worked flawlessly. I could never get creative asio to work.

So you had Foobar's OutPut set/selected to Asio (dll, eg. plugin) --> and what "Device" had you set for Asio_dll? Wasn't that named as "Creative ASIO" or "SB Audigy ASIO" (just hoping not Asio4All)? Creative ASIO just can't work without plugin installed on Foobar. Or can it?

For grins I went back and looked at the ASIO again. This time using the dll version of the foobar plugin (as I had in the past) and the Creative ASIO driver but get the dreaded

INFO (CORE) : startup time: 1531 ms
INFO (CORE) : opening file for playback :

error message.

Where do you configure the Creative ASIO? Will look in the creative panel.

OK went back to the Output Options and upped the output to 32 bits and the Creative ASIO works.

WOW - now I have a new favorite, the sound became smooth and much more dynamic, none of the harshness of ASIO4all and I prefer the sound to the KS.

Thanks for making me look into that again.

BTW my system is XFi <coax> Headroom Desktop DAC/AMP (both desktop modules) -> HD 650

Sounds like you should set the output data format to 24-bit, rather than 32-bit.
post #43 of 57
I think you need to use 32bit output. From what I remember, that's the only one that worked.
post #44 of 57
LOL figured that out and was reworking it as both those messages came in.

Thanks

The Creative ASIO really makes my system come alive. It was ok with KS, but I was really not overwhelmed. I am now.

PS, I still can hear some of the computer noises coming into the music. I need to find where some of the "click" noises that accompany websurfing are enabled, and disable them.
