crash when selecting USB device

[4AM]

hi,
i have installed the driver and tried to select my usb soundcard in the panel.
when i use the internal soundcard all works fine
but with the external one (m-audio mobile pre usb) my computer restarts when i try to select it.

any idea?

did i miss something?

A crash like the one you are experiencing is, first of all, a driver/OS issue, since there is no actual kernel mode code in ASIO4ALL.

There may, however, be ways to work around that matter, which would require you to run a number of debug versions of the ASIO4ALL driver on your system, in order to narrow down the condition under which the OS/driver would bomb.

And, of course, that would mean a couple more OS-crashes along the way.

If you're prepared, send me a PM with an address that I can send stuff to.

Hi to all
I have same problem, with m-audio mobile pre USB.
My system crashing when i set device in the driver windows the A4A

As this seems to be a more general issue with M-Audio USB drivers, I am going to look into this trying to find a catch-it-all workaround.

I have a sneaking suspicion WRT what might be the cause and in order to verify/dismiss this theory of mine, I would ask you guys to try the following:


1.) Uninstall ASIO4ALL v2

2.) Open your favorite audio app and create a test project with the project sample rate set to 48Khz! Save and exit.

3.) Download and install ASIO4ALL 1.8

4.) Launch your audio app, load the test project and make sure ASIO4ALL (v1.8) is selected as the ASIO driver.

Does it still crash? If not, the workaround would be pretty easy to implement in v2.

The reason for my theory is this:

In the specs of the Mobile Pre they write: 16Bit/48KHz analog playback, but further down there is something along the lines of "Supported Sample Rates: 8, 11...<a lot more entries>...48Khz", which may mean that they do driver level resampling that does not really work on the WDM/KS interface of their drivers at least.
