I guess it does a open() on the sound device. These interrupts numbers are just because of starting amarok, i don't even play a song in this software. So here a two options: 1.) fix amarok to open the sound device when it's needed 2.) fix the kernel sound card driver to setup everthing, when an application want to put data on the device what do you think about this? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
