it seems like you didnt use the plug plugin correctly.

suppose your dmixer pcm is called ossmix then you have to put the
following in your .asoundrc: 
pcm.fixed {
    type plug
    slave {
    pcm "ossmix"
    rate 48000
    }
}

the a/v synch will be correct then. however the plug plugin doesnt
resample very good. you will notice noise and occasional cracks in the
sound. so report that to alsa devs if you want. otherwise use srate
48000 which has way better quality than the plug alsa plugin.
