Winsound not working in 64-bit Session-based interface

Hello, I'm using a new version of Matlab (R2011a, 64-bit, win 7) and the whole "session-based" data acquisition environment it totally new to me (and not user friendly at all...). I'm trying to put together a demonstration using "winsound", something I was able to do with older versions of matlab. However, the sound card does not show up in the daq.getVendors list.

I've tried to run Matlab in windows XP SP 3 compatibility mode and that still forces me to use the new "session-based" environment (uggg!).

How can I get the sound card to work like it's supposed to (ie: in previous 32 bit versions of matlab)?

Can I force my 64-bit version into 32 bit mode to do data acquisition?

Can I just default to the legacy system? The new session-based system supports next to nothing and it's very chunky and not user-friendly at all.

On 64-bit MATLAB on 64-bit Windows, you can only use the session-based interface. The session-based interface furthermore works only with CompactDAQ boards, so not winsound.

To use the legacy interface with winsound you can install the 32-bit version of MATLAB on your 64-bit Windows. Please also note the information under:

do you know if/when the data acquisition toolbox will be supported on 64-bit machines? CompactDAQ boards are such a limited part of the hardware spectrum for data acquisition, compared to the serial, PCI, PCIe stuff they supported under the previous versions. I'm actually shocked (and dismayed) that 64-bit systems cannot make use of legacy hardware (legacy meaning hardware from 6 months ago in some cases).

And I'm at a university that supports only the 64-bit version for windows 7 which is a real pity.

You can always contact MathWorks directly in order to find out more. You will probably not get exact information about when the legacy interface or non-CompactDAQ boards will be supported but it is always possible to submit enhancement requests.
