Just figure out something unique for your sound devices, and create some |
| 8 |
rules like the other persistent rule generators do. PCI device id |
| 9 |
perhaps? |

If you have problems with this, try asking on the linux-hotplug-devel |
| 12 |
mailing list. The people there can help you out. It would be good to |
| 13 |
have some rules for sound devices like this, as you aren't the first to |
| 14 |
ask about it. |

Yeah, I have a box around here like that too :( |

PCI device order is usually quite stable, unless you start to use PCI |
| 28 |
hotplug, or change cards, or update your BIOS. If you did any of that, |
| 29 |
then it would start to get unpredictable. |
