Dear All, I am new to this Advanced Linux Sound Architecture (ALSA) driver. I developed a few drivers in Linux kernel environment for PCI based devices which are of type character and block. I am going through the following link for writing a driver for my custom sound card. http://www.kernel.org/pub/linux/kernel/people/tiwai/docs/writing-an-alsa-driver.pdf I have a doubt about the Linux sound driver architecture. I need to develop the driver with mixer, player, recorder, MIDI etc. components. Do I need to develop these components in single driver OR Do I need to develop as a individual component (one driver for one component). I looked into the /usr/src/linux-2.6.35/sound directory. I did not understand it completely. Is there any driver (sample) which I can go through? Please let me know. Any help greatly appreciated and helpful to me. Thanks and Regards, Srinivas G _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
