Hi all, I have a problem that I need help from the ALSA experts. I want to write an alsa shim .ko which creates multiple cards. Let's assume 2 cards. My program calls snd_card_create() and snd_card_register() two times. I also has 1 PCM for each of these card. After install the .ko to the kernal, I see the /proc/asound has card0 and card1. But the "aplay -l" sees only card0. The snd_card_next() only returns 0 (i.e. 1 card). What did I miss in my program? The /dev/snd/ has only hwC0D0 and pcmD0C0p. I am a beginner in ALSA, so I appreciate if you can give the explanation in detail. Thank you, _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
