Anyone having problems here. My devices no longer show up. Audio works fine. Note that 1. /proc/asound/cards shows ALL devices 2. cat /dev/midi# show events from the keyboard. The keyboard is through a USB driver. I get snd-usb-audio install error from modprobe on bootup. Attempt to rmmod say it is in use. However: Kmid shows no devices, neither does Rosegarden. Jackqtl has no active connections but show devices on it patchboard. Connections made here are "silent". Audio is working without a hitch.
