WASAPI, WASAPI-Event drivers

who knows

-how many channels (5.1 possible or stereo only?)
-sample-rate: what sample rate is supported?
-bit-depth is how much possible?

It depends on your hardware.

Hi Matt

I took a look the the explanation.

After this WASAPI should support what the hardware supports.
However with a motu828mk3hybrid, JRiver wants to switch back to two channels. Also I cannot run sample rates 96kHz, 192kHz.

May be its just theory?

I don't have first hand  experience with that device, but our recommendation is to use ASIO if the device has an ASIO driver which the MOTU does.

So you might start there.

I recommend you use ASIO. It works properly which is why it is recommended first in the link Matt provided. Some pro audio devices only show up as multiple pairs of stereo channels when using WASAPI. My Steinberg is 8 channels, but with WASAPI it only shows up as 6 channels.

I looked at the Motu manual and it shows that the WDM driver (used by WASAPI) is multi-channel. Do you have the latest driver installed? Page 55 and following in the manual show how to set up the WDM driver for multi-channel use.

WASAPI doesn't automatically change the sample rate with some devices like ASIO does. In your MOTU Audio Console you may have to set the sample rate manually if you want it to work with 96 and 196 kHz. Also, "Enable full Wave support . . ." should probably be unchecked.

I just tried with WASAPI with the motu828mk3hybrid.

I guess I better stay with ASIO.
