How can I check if CONFIG_SND_DYNAMIC_MINORS is enabled, and enable it if
it is not already?

I've been having a lot of trouble assigning 10 USB soundcards, and it's
been doing fishy things when I change who's plugged in to which usb hub.
ALSA recognizes all the cards, but some of the hw:x,y plays through the
default hw:0,0. Also PulseAudio fails to recognize those same cards as
"sinks" and only recognizes their microphone capabilities.

Cheers
Cyrus

Look into the .config file in your kernel source tree.

It's not easy to distinguish devices that do not have a serial number.

This implies CONFIG_SND_DYNAMIC_MINORS is enabled.

You mean, to the wrong device?

How did you test this?

Check that the minor numbers in /proc/asound/devices match the actual
minor numbers in /dev/snd/.
