But that is precisely the problem. The framework that manages the insertion and deletion of modules notes that my module has a usage count that is > 0 (in my case it is 2, which I'm convinced is because the card has been registered with ALSA), and refuses to free the module. So there is now way any unregister_card call can be made when my module is freed, as due to the usage count it would never even be attempted. I suppose one way would be to have a specific call into the module which unregisters the card, and the module could then be freed as usual afterwards, but it seems like a bit of a hack. /Ricard -- Ricard Wolf Wanderlöf ricardw(at)axis.com Axis Communications AB, Lund, Sweden www.axis.com Phone +46 46 272 2016 Fax +46 46 13 61 30 _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
