Playing different audio files through different output channels of soundcard

Hi, I have the TASCAM US-16x08 soundcard having 8 output channels. How can I play 8 different music files from the computer through these 8 different output channels?

See the appropriate TASCAM documentation.

TASCAM is not mentioned in the MATLAB online documentation or Add-Ons references.

@star Strider Thank you for replying. Isn't TASCAM like any other sound card? And wont there be a way to access the different channels independently?

I tried using the example:

openExample('daq/multichannel_audio_generation_session')

The problem is that I can only get output through channels 1 and 2. There are no signals coming through channels 3-8. (The example is to get output on 1-6 channels and I don't get any output on 3-6 channels). Is there any suggestion so as to obtain those outputs?

My pleasure.

To the best of my knowledge, MATLAB only supports two channels, since that is apparently all that most soundcards support. The Audio Toolbox may have more options. (I do not have it, so I have no experience with it.)

@Star Strider Thank you. Will explore more.

Apparently, if the output channels have to be used properly, TASCAM US-16x08 have to be used with audioDeviceWriter having 'Driver' as 'ASIO'. It didn't work with 'directsound'. The code below works fine.

deviceWriter = audioDeviceWriter('Driver','ASIO');

getAudioDevices(deviceWriter)

deviceWriter.Device='US-16x08 ASIO';

deviceWriter(Audio_Variable) % Audio_Variable should be a matrix having number of columns = number of channels and rows having audio data corresponding to the channels for default channel mapping (each column maps to each channel). Else need to customize.
