[alsa-devel] ALSA driver fails to creat ControlC1 and others...

I am having problem creating 2nd ALSA sound card driver I developed:

I found snd_ctl_dev_register() in control.c is called successfully but I do not see the 2nd sound card entry below:

# ls /dev/snd
controlC0  pcmC0D0c   pcmC0D0p   pcmC0D1c   seq        timer

And I saw a suspicious message at the end of boot steps:

Unmuting sound device: [FAIL]
Starting dropbear sshd: OK

Well, this happens with one file system, and with another file system, the 2nd card entry is created correctly as below:

# ls /dev/snd
controlC0  pcmC0D0c   pcmC1D1c   seq
controlC1  pcmC0D0p   pcmC1D1p   timer

And I don't see that message.

Anybody has some suggestions?

Thanks a lot in advance.
