[wdmaudiodev] Re: APOs and multichannel inputs

Thanks for the clarification Frank. However, I wasn't concerned about
multichannel output, but rather multichannel input to an APO. Any
multichannel files I play still set the input to my APO to 2 channels.
Do I need to do something specific to support multichannel inputs to an
APO?


Thanks,

Jeff

Jeff, your view is correct. You should normally not have other speaker
configurations available if the physical hardware and driver support
only stereo. You do not need a multichannel output to run a multichannel
virtualization algorithm.

Hi Dugan,

 

Thanks for the reply. I have not selected 5.1 out, because the hardware
only supports 2 channel out. The "Speaker Configuration" list box
doesn't even allow me to select anything other than stereo.

 

This makes sense to me, since only 2 channels are available at any time.
I think it would be pretty confusing for the user to have to select 5.1
output for virtualization. However, that begs another question - should
I still be able to select 5.1 output even with 2-channel hardware?

 

Thanks,

Jeff

It should be possible - the built-in HDAudio system effects do this (for
speaker virtualization).  Forgive the basic question, but have you
selected 5.1 output for your device in mmsys.cpl?

        Hi everyone,

         

        I'm developing an LFX APO that includes a multichannel to stereo
virtualizer. However, on a 2 channel codec, I'm having trouble getting
any multichannel input, even though the source is multichannel. Is it
possible to get multichannel inputs into an APO (when the codec is
stereo)?

         

        Thanks,

        Jeff
