[alsa-devel] snddevices issue
Hello,
I find that the device nodes created in the /dev/snd for Control, Timer and pcmC0D0 have different minor numbers from the class devices created by the ALSA core. I just did kernel prints to capture the minor numbers of audio Control, Timer and pcmC0D0p creatd by ALSA core and found that they are different.
My ALSA core version is ALSA 1.0.13 and the snddevices file is also from the ALSA 1.0.13. How do I do a workabout for this?
Regards; Aadish

The help text for the --enable-dynamic-minors option (when using the alsa-driver package) or the CONFIG_SND_DYNAMIC_MINORS option (when using the in-kernel ALSA) says that this can be used only when the machine is running udev. (If you are actually running udev, you don't need the snddevices script).
I just did kernel prints to capture the minor numbers
These numbers are also available in /proc/asound/devices.

The question is whether alsa utilities will run on nodes like pcmC0D0p in such a situation?...The device nodes created under /dev and in proc file system show different device numbers (minor numbers are different).
