snd_pcm_hw_params_any failes but aplay works

["Phil Wiggum" <p1mail2015@xxxxxxxx>]

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)

snd_pcm_hw_params_any return fails!

 

I guess I'm missing something....

~/.asoundrc/20-Dual.conf:

    @args.CARD { type string; default "U7" }
    type hw
    card "$CARD"

    @args.CARD { type string; default "U7" }
    type route
    slave.pcm {
        type multi
        slaves.a { pcm "type-hw:CARD=U7"; channels 2 }
        slaves.b { pcm { type plug; slave.pcm "type-hw:CARD=HIFIRef"; } channels 2 }        #  plug needed: to convert bits format!!

        bindings {
            0 { slave a; channel 0; }
            1 { slave a; channel 1; }
            2 { slave b; channel 0; }
            3 { slave b; channel 1; }
        }
