Btw, you never told me which is your Os ? win 7 or win 8 ?

 
I'm using Windows 7. Maybe that's part of it...I haven't used Windows 8.1 because of all the stories I've heard about driver problems with a variety of hardware devices (not just interfaces, printers etc.).
 

I am working fine with the new Asio drivers from this Australian programmer. He did a great job , and gives Tascam much further options ! Yes you should try it really. It has a total free to test drivers. It gives also the possibility to change the audio stereo from left to right channels inside the software , to have only one or two mono outputs very useful for testing your mix before radio mono conversion , giving each program different configuration and to save the profiles and many more.

 
Well, I prefer using ASIO drivers so I'm not interested in checking out a non-ASIO solution (Paul P is right, it's a wrapper, not true ASIO). As to flipping channels, generating mono, etc. all that and more can all be done with Channel Tools in the master bus which is more flexible than opening another app. I'll alert TASCAM to this thread, but so far you're the only person who's reported this and I can't reproduce; I don't know if there's sufficient info in what you've posted to let them make an educated guess as to why it's not working on your system. As I said, I can have SONAR playing back audio and several Windows apps playing back audio and it's all fine. The only time I could experience what you're experiencing is if another driver is installed. (However like CactusMusic noted, there may be sample rate issues and in that case, all bets are off.) 
 
Finally, note that some interface drivers simply will not work properly if ASIO4ALL is even installed in a system. I can't verify if that's the case with TASCAM because I keep ASIO wrappers as far away from my system as possible. This forum is littered with posts from people who experienced weird SONAR or interface problems, and uninstalling (not just turning off ) ASIO4ALL solved them. I presume other wrappers might be subject to similar issues. But again, everything is working fine here so I have no real incentive to investigate further. Maybe TASCAM will have some advice they can give you.

I never used and I don't like Asio wrappers as well. I had my M-Audio 1010Lt for around 14 years, never had a problem. Back in that period everyone was talking highly of M-Audio fantastic audio drivers. 
 
I have a Dat and pro tape  from Tascam. I was a happy Tascam user. Well It's the first time I bought a tascam usb audio driver interface. 260 euros in my country , and I wasn't happy with it. I don't think they accept refunds since their drivers are not working with my system , and as said I am a technological Guru I know very good how to handle hardware and software together.  If the drivers had only the conflict audio problem , then my computer should boot and restart perfectly. But no it didn't,  cause of that audio driver problem it couldn't reboot or restart.
I had to do something to stop feeling bad about my purchase . Those drivers fixed everything , even now I can boot and restart perfectly. I don't see the reason not to use those asio drivers ? It's a winning scenario for me and for Tascam since I am not planning anymore to ask for a refund and most of all I feel happy again. 
 
As I have checked all other devices from Tascam , they are only producing maximum 3 drivers updates in 2 years time. M-audio was producing around 4 per year . 
I am not saying they are doing that on purpose . They have to understand that technology advance so fast, they need to catch up. I have written all my setup details at the beginning of this post. If you forward my post to them , I believe there are more than necessary details to understand what's going on. But if not I will be happy to send them my email for further investigation and to help them fix their driver issues. 
 
Thank you again for all your great support and details. 
 
ps. audio4all and another asio wrapper didn't worked with the tascam.

On what information are you concluding that your australian driver is not an ASIO wrapper ?

Because they (?) are not asio driver(s).  How could they be ?
 

Well, in any event I'm glad you got it resolved. We'll see what TASCAM says. Meanwhile, because of your question, I found out how to have all kinds of audio playing at the same time if I ever need it!

I am glad that something positive came out for you too. It's true that when looking things in different way many times gives good results. Always a nice conversation between positive people gives always back. 
I really like Tascam , it sounds good as well compared to my previous Delta 1010 lt , and I wasnt sure if USB racks could compete PCI audio interfaces, but it did very nice. Time will tell for sure. 
By the way it's been like 4 days and I haven't received any reply from Tascam yet.

I just noticed this. Are they currently installed on your system? That's the kind of information TASCAM would need to know. TASCAM may be one of the companies whose drivers will not perform properly if ASIO wrappers are installed on a system. 
 

I agree with Etostone on the point that if it solves your problem and does not cause new problems, then the solution he has found is a good one. Technically it may not be the best, but he has a system that makes him happy.
 
My problems were really setup problems and the only fault I find with Tascam/Teac is that I feel the documentation did not explain the settings well. The two previous Tascam units had very good documentation and I had no problems installing them with Sonar. I am fairly technical and have worked with interfaces and DAWs for a number of years and I still found the options a bit confusing. I will now do what I have always done in the past ... record all my settings so that I don't have to think so intently if I ever have to restore my settings.
 
It is great to have an active board with helpful people, thanks again.

No , since those didn't work I unistalled. Did you forward the whole post to Tascam yet ? If not , is it possible to give me their email so I can email them ? The one from their support seems that it does not work. 

I just sent off the thread URL for comment. I'm still confused as to why I can play as much audio as I want, including SONAR running ASIO and Windows running multiple sound sources, and you can't. I don't know what difference in our systems would account for that...maybe TASCAM will be able to reproduce your issue and report on a solution.

Thanks Anderton. I wish I knew as well. Probably the new windows 8.1 pro 64 , my new motherboard and CPU , in comparison with Tascam are not combatible somewhere between. 
Let me know if you get any reply from Tascam.
