Maybe putting each component into its own module would help. I'd rather not as there's no real gain from it (the constituent drivers cannot be used separately or in any other combination), but perhaps that is the only way to go. > Anyway, you should be able to unbind the driver: > <https://lwn.net/Articles/143397/> Yes, that works. After unbinding the driver, the usage count drops to 0, and I can successfully rmmod it. So at least that's a workable solution. It just seems to me that there's something I must have missed, as there should be a mechanism to do this automatically when a module containing a driver is rmmod'ed. /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
