ASIO Bug?

Eminos · Mar 7, 2003, 12:04 PM

I have a huge problem!

When using Cubase SX for a while, the ASIO inputs sometimes switch...I think randomly...right now it showed signal on my Aux 2 track, when it should be Mic 2...when I restart Cubase everything is OK, for a while...

I had this problem in 3528, 29, 30...(the drivers before that I don't know...)...and in Cubase SX 1.01 and in 1.05.61 (latest)...

Greatful for help...

BTW, uninstalling MotherBoardMonitor solved the Clicks and Blips problem...now I can use 2.5 ms latency...:)

If I enable all ASIO inputs on my SBLive 4620 the inputs shift/permutates. Does this happen to you when you enable all inputs?

Yes!...sometimes everything works great, and when I enable some other inputs, then all the inputs fucks up...

Anyway, I always use this config...all are always enabled in Cubase...

ASIO 4/5 - AC97/(Line In) (Digital-Drums)
ASIO 6/7 - Line2/Mic2 - (2microfones via an external mixer)
ASIO 8/9 - Aux 2 (keyboard)

This workes ok...but if I move the inputs to 6-11 or 8-13 or 10-15 everything is messed up!...

Why?!?!...

And the problem about random switching inputs (without enableing/disableing inputs) is still there...!

BTW, what is the problem about ASIO 0/1 and Live-Cards?!

I have a similair problem. Everytime I open Cubase I find my inputs have been mapped differently.
It doesn't make any difference whether I have all inputs enabled or not, in either Cubase or the KX DSP window. I have all inputs enabled in Cubase by default now, as it makes it easier to find the various soundcard inputs.
I have a Soundblaster Live! 5.1 and Live! Drive IR. The card is marked SB0100, but the modelled displayed in the corner of the mixer is SB0102 5.1 [cc00].
The problem has been occurring with versions 3530, 3531 and 3532 (I haven't tried any earlier versions). I am using Windows XP and Cubase SX 1.05.
Has anyone found a solution to this?

I've found a possible fix for this.
I noticed that ASIO 0/1/2/3 aren't connected to anything in DSP window.
I then disabled these inputs in Cubase (Devices>VST Inputs) and now have stable inputs!
The inputs aren't appearing where you would expect them to from the DSP window, but they are staying put!
I'm using the default set up in KX for the DSP window connections etc...
I obviously haven't tested this for long, if I have any problems I'll post again.
Hope this helps.

this is a known issue on most 'Live5.1' boards
if you disable -any- input, it should stabilise the things a little (afair)

Thanks for your response Eugene. After checking this for a while I can confirm that the inputs are more, but not completely, stable.
I did check under known isssues before I searched the forum, but couldn't find any mention of my card.
Is this the same issue as "SB006x cards have an issue with ASIO input and output mappings that can't be fixed (a hardware problem)." Or is there likely to be a fix in future?
Is the behaviour of the inputs etc... the same as this with a SB0060, or worse? I ask as I have an SB0060, which I'm not using because of this known issue.
Thanks for your help, and especially for these great drivers!

>> Is this the same issue as "SB006x cards ..."

yes, this is the same issue
all Live 5.1 cards seem to have this issue

Thanks once again for your reply Eugene.
I seem to have happily stumbled across configurations of KX and Cubase SX that give me completely stable inputs!
I can’t pretend to understand why this works, however I have tested the stability of this set up as extensively as I can within the time available, in ways which showed up the flaws in my previous attempts – and my inputs in Cubase SX have remained completely stable.
Unfortunately I have found that I can’t simply tell you to enable such and such ASIO inputs in KX, and such and such inputs in Cubase. Experiments along these lines have led to inputs as unstable as ever. Instead I’ll try to take you there step by step, by the route that I arrived.

To start, a recap: I have an OEM SB0100 with a Live Drive IR, recognised by KX as an SB0102, I’m using Cubase SX 1.05 and Windows XP. I am currently using version 3531 of the KX drivers.
I initially had all sixteen channels enabled in Cubase, and set up as audio tracks in the main project window, so that I could easily find my moving inputs. I was using the default settings in KX for my card.
I then disabled inputs ASIO0/1/2/3 in Cubase (at Devices>VST Inputs) allowing Cubase to remap the effected audio tracks, which gave me stable inputs if I didn’t reboot the computer – a considerable improvement! These were not mapped as you would expect them be from the KX DSP window, but they were more stable.

Now to credit the real author of this fix. I read the following recent thread on the forum: kx asio nuendo no fx return
s3n71nel seemed to have stable inputs in Nuendo, so I decided to try his input settings. In the KX DSP window I disconnected and reconnected soundcard and ASIO inputs in order to give me a set up which seemed to conform to his input settings:

“Here is how the inputs and outputs look in Nuendo

inputs

ac97(mic) > kx in 10/11 (=Nuendo IN 11/12)
lin2/mic2 > kx in 14/15 (=Nuendo IN 15/16)
Aux2 > kx in 04/05 (=Nuendo IN 05/06)”

I then disabled all but these inputs in Cubase (Devices>VST Inputs), allowing Cubase to remap the effected audio tracks. Returning to the project window, I noticed that audio tracks 11 to 16 used all six inputs in a convenient block, so removed the remaining tracks..
I then proceeded to test the stability of these inputs, repeatedly closing and opening Cubase, doing warm and cold boots of the system, over and again until my eyelids were getting heavy(2am) and I was sick of it!
The inputs remained completely stable!

They are not mapped exactly as you would expect them to be in the KX DSP window.
In the DSP window: AC97 to ASIO10/11
Line2 to ASIO14/15
Aux2 to ASIO4/5
In Cubase: ASIO10/11 is AC97
ASIO 4/5 is Line2
ASIO14/15 is Aux2
They have remained completely stable so far though. So much so that I have made this my default project, and renamed the audio tracks to their physical inputs.

For anyone who wants to try to replicate this I will attach my Cubase default project, my KX settings and a screenshot of my KX DSP window and my Cubase VST Inputs window. I think the KX settings will only work if you have exactly the same card as me. Also, I have tried to take shortcuts to replicate this, but none have succeeded, so to be sure it would be best to go step by step.
Lookng at the DSP window, you’ll notice that I haven’t completely disconnected all unused physical inputs from everything else. This was just the way things turned out as I disconnected and reconnected things. A bit sloppy, I know, but it’s working – so I’ve decided not to touch it!

I hope this helps anyone else suffering from this unstable inputs problem, and that it helps shed some light on this conundrum for more knowledgeable heads than mine!

P.S. I'm having trouble attaching the archive containing the settings, screenshots etc..., are attachments permitted on this forum. I would try rthe step by step approach, leave a reply here if you have problems replicating my set up.
P.P.S. The difference I referred to above in the DSP window is that Optical L & R are still connected to xRouting In10/11
Good luck!

just thought i'd add my experience with logic here.... all my asio inputs are totally stable and correspond exactly with the dsp inputs (well, shifted by one, since logic starts inputs at 1 not at 0) as longas i just avoid asio 0-1.... using those makes everything 'wonky'

paulf · May 28, 2003, 04:00 AM

I get the same using a SB Live card (not 5.1) and Sonar XL 2.2

I have three pairs of inputs live (Line In, CoAx in and CD SPDif in)

If I enable one to record, it's normally in the correct place. If I then enable a second pair to record, then this normally gets the input from the 'first' input, and the first track get's the input from the 'second' input.

It's not a major problem, but it does mean you have to double check what input is on what track to make sure you get them right !!!

doppler · Jan 17, 2005, 07:51 PM

Shouldn't this issue with SB0100 (and other Live! 5.1) cards be explained on the kX website? It only says this legendary "routing issue"-line, which is not too helpful for starters-up in kX-World (like me)...

So this thread here is actually very useful. I will try the tricks with Cubase written here tomorrow. Hope it works
