I suppose at you are on debian, maybe at a debian user know more as me about the specific debian configuration. The problem here is at each distribution have its own way to do the alsa configuration and at most distributions don't have any multi sound cards config doc (and it must be reported as a bug because multimedia is becoming a very important part of the computer experience). > so i'm here asking you for a solution > tnx in advance > M@ > It is not the first time at this problem come on the list and it will be great if we can solve it. According to some not so old responds, it is 2 ways to do that, at the system level as you are doing or at the user level as gnome is doing. I personally think at the right solution for most of multi sound cards configuration is a mix of both ways. First, get the system to load the sound cards in a given order. Settings in /etc/modules.d or whatever your distribution is using must be able to do that. If not, it is a bug and must be reported to your distribution. Second, let the user change it if he want to. For what I know, Gnome can do that but I don't use it. And the other wm cannot do that. So here it will be great if a gnome user explain how he adapt the cards order to his need, and if someone can explain how to do that with the other wm. If we succeed, it will be great to incorporate the result of this thread in the alsa documentation.
