[SOLVED] No sound in flash

In trying to get my MIDI keyboard to play in Rosegarden, ALSA stopped working like it used to. I used a USB MIDI cable to connect my MIDI controller to my computer.

Looks as if snd-usb-audio is now card 0. To make a long story short, finally got sound to work by creating a /etc/asound.conf

pcm.!default {
        type hw
        card 1
}

ctl.!default {
        type hw
        card 1
}

Everything seems to be working fine except for flash, which I'm using nspluginwrapper. Tried reinstalling nspluginwrapper and nspluginwrapper-flash, still no sound. I'm at a loss.  Here's some pertinent info:

lrwxrwxrwx 1 root root 10 Mar 25 18:18 /dev/dsp1 -> sound/dsp1

FIXED
I re-edited my /etc/asound.conf:

pcm.!default {
        type plug
        slave.pcm "dmixer"
}

pcm.dsp1 {
        type plug
        slave.pcm "dmixer"
}

pcm.dsp0 {
        type plug
        slave.pcm "dmixer"
}

pcm.dmixer {
        type dmix
        ipc_key 1024
        slave {
                pcm "hw:1,0"
                period_time 0
                period_size 1024
                buffer_size 8192
                rate 48000   #many new cards are 48000 only
        }
        bindings {
                0 0
                1 1
        }
}
        

ctl.dmixer {
        type hw
        card 1
}

And flash is now working.
