Device problem on Reaper

[bongano]

Config:
Win XP Pro
Realtek Sound Card
Amplitube 2
Reaper
ASIO 2.9

Everything is ok playing with Amplitube Standalone.
When I turn on Reaper with Amplitube on, on Reaper device config Input device appears with red X and unavailable.
If I turn off Reaper, everything turn back ok.
Any ideas?
TIA

That is correct behavior.

Only one application can use ASIO4ALL at a time. Read the FAQ.

In order to achieve low latency ASIO4ALL gets exclusive access to the audio channels that you select in its configuration.

Sry for bad English.

Is it possible to check which Applications take the availability of the Asio4All?

I got the problem that a application take the functionality of the Device and i don't know which one.

Systemsounds OFF. All Programms (I can see) OFF. But "Unavailable"

Thanks,
Kai

It is quite easy to see. Each application that uses ASIO4ALL will have a seperate icon in the lowerright icontray.

By the way.. other applications could also exclusively lock your audio hardware.
