Dear all , The tutorial below states that ""Each card device can have up to four pcm instances" https://www.kernel.org/doc/html/v4.19/sound/kernel-api/writing-an-alsa-driver.html#pcm-interface <https://www.google.com/url?q=https://www.kernel.org/doc/html/v4.19/sound/kernel-api/writing-an-alsa-driver.html%23pcm-interface&sa=D&source=hangouts&ust=1573928998988000&usg=AFQjCNGmZgiENmLej2aBTQvp-tspn3u8sg> I am getting confused with the number '4' . I thought we can add 8 pcm device files by default. By setting 'CONFIG_SND_DYNAMIC_MINORS=y' , we can have more than 8 pcm device files. Does that tutorial mean only 4 pcm devices running at the same time ? Thanks a lot, Xinhui, _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx https://mailman.alsa-project.org/mailman/listinfo/alsa-devel
