I discussed this with our alsa developer. He proposed to tied:
- /dev/snd/timer      -->  first sound card (alsa.card: 0)
- /dev/sequencer      -->  first sound card (oss.card: 0)
- /dev/sequencer2     -->  first sound card (oss.card: 0)

I reworked the patch for this and *.device_file/*.physical_device.
