I think you just need to add -f / -F to sndiod

     -F device
             Same as -f except that if the device is disconnected, the one
             given with the previous -f or -F option will be used.

     -f device
             Add this sndio(7) audio device to devices used for playing and/or
             recording.  Preceding per-device options (-aberwz) apply to this
             device.  Sub-devices (-s) that are applied after will be attached
             to this device.  Device mode and parameters are determined from
             sub-devices attached to it.  If no -f option is used, sndiod will
             use rsnd/0, rsnd/1, ..., rsnd/3.
