# aplay -D hw:0,3 test.wav
Playing WAVE 'test.wav' : Unsigned 8 bit, Rate 11025 Hz, Mono
aplay: set_params:857: Sample format non available
4) How can we use "aplay" to play test.wav on the card 0 device 3 ?
The problem with the WT device is either a bug in the DMA code or a
bad route. The WT DMA works almost indentical to the ADB DMA engine,
but with its separate set of registers. I have looked over and over
uncountable times, without finding any clue. The most uncertainty is
in regard of the WT routes. The only thing i know is that each WT bank
has 32 channels, each channel with some processing capabilities
(pitch, delay, filter, gain, etc) and there are 32 + 6 sources toward
the routing bus for each bank. I guess that the first 32 sources are
mapped to each individual WT dma channel and the other extra 6 sources
are some kind of downmix of the entire bank. But i am still clueless
about why having 32 individual sources for each channel, if we have
only 32 mixer inputs, and many of them are already being used ? There
is no way to make use of all of them, thats why i guess that there
must be some downmix of each WT block available somehow.

2) How did you perform your "WT DMA" test ?
