Okay, with Foobar (for example) I have often THOUGHT I had ASIO going, but only CONFIGURED it, and another plugin was still active. Are you SURE SURE you're using ASIO for Foobar too? Winamp is more of a no-brainer.
This mixing is not consistent with 'typical' ASIO operation. SOMETHING is doing mixing. Question is: What?
Cheers,
Presto
I have an M-Audio Audiophile 2496 and the Delta 410. Both allow multiple clients to access the ASIO driver at the same time. There is such a thing as multi-client ASIO drivers, but I guess the question is if the ASIO spec allows multi client or if it is just supposed to allow exclusive access..
ASIO can be multiclient or not depending on implementation by the manufacturer. It takes a bit of DSP on board of the card itself to correctly mix the different streams from multiple clients (aplications). Some cards will even allow access from two different clients through different drivers. For example the Emu cards will accept a stream from WMP through DS and pass it on to ASIO bus while simultaniously playing back sound from an app like Console through ASIO driver.
My RME card will accept multiple client ASIO streams but only if they are at the same sampling frequency.

Are you SURE SURE you're using ASIO for Foobar too?Yes, just checked again. I suspect flakey M-Audio drivers. The last second or so of the last song on a playlist in Foobar gets cut off with native ASIO. ASIO4All has no such problem, nor does DS.
But yes, native ASIO on both pieces of software.
Edit: I think I am going to get rid of this Transit POS. I originally got a Squeezebox and bought the Transit only to do in-room frequency response measurements with my laptop. But the SB kicked the bucket, so I set up my laptop with the Transit going into the DAC1. I think I'm going to get an E-MU 0404 USB to drive the DAC1.
Hey Andy,
I agree with Presto that it is somewhat easy to THINK you have asio going, but not in Foobar.
Would it be too much trouble to post a few screen shots so we all can rule that out? Otherwise, you could maybe have the same issues.
I can switch back and forth between DS and ASIO and have the truncation of the end of the last song come and go. I know that ASIO is present because I can identify this bug by moving the slider to the end of the last song in the playlist and see if it gets cut off.
I always click "Save All" when changing the output device if that's what you mean. After doing this, the changes "take" when you stop and resume playback.
Hey AC:
Are you using two different instances of Foobar at the same time? If so, are they the same version? Do they use the SAME PROCESS NAMES??
See where I am going with this??
Whenever I do tests on ASIO or KS (to check for mixing) I always use Foobar for one ASIO source and Winamp for the other. Why? I am usually very reluctant to run multiple instances of a program simultaneously.
Get back to me...
Cheers,
Presto
Hi Presto,
I'm only using a single instance of each program. I just tried to launch separate instances of Foobar, and its default configuration won't allow this. I can't find an option to allow multiple instances, but I haven't looked very hard.
So the configuration is - single instance of Foobar2000 (0.9.5 Beta 5), and single instance of WinAmp.
I know that proper ASIO behavior is to not allow what I'm seeing, but I suspect the drivers of the M-Audio Transit are not a proper implementation.
I just ordered an E-Mu 0404 USB last night.
"I just ordered an E-Mu 0404 USB last night."
Know when to walk away... know when to run? :o)
Who would have thought to test this on a USB device?? Good work. This phenomenon could have significant repercussions for other USB based devices - especially those from our friends at M-Audio!! ;)
Cheers,
Presto
