Hi!
I have following setup where 2 cards play in parallel.
It works nice with 'aplay -D Dual ~/Music/wav/test-16-44100.wav'
But it doesn't work with Kodi.

xbmc/cores/AudioEngine/sinks/AESinkALSA.cpp:1463
/* ensure we can get a playback configuration for the device */
if (snd_pcm_hw_params_any(pcmhandle, hwparams) < 0)
/* ensure we can get a playback configuration for the device */
if (snd_pcm_hw_params_any(pcmhandle, hwparams) < 0)
snd_pcm_hw_params_any return fails!
I guess I'm missing something....
