ALSA sound stutters, OSS emulation doesn't ???

Very strange...

My asound.conf file is below.

I have a certain setup, and sometimes it makes my sound output stutter a 
little. It isn't much, and doesn't seem so all the time, but it happens 
always at the same time for the same sound samples.

I suspect this is due to the a52 plugin.

But the odd thing is, why doesn't OSS have any stuttering? I mean, it's just 
an extra layer on top of ALSA...

If at all possible, i'd like not to have this stuttering in ALSA. for the 
moment, i'll just use oss emulation in xine.


asound.conf:
----------------

pcm.ac3_51 {
    type a52
    slavepcm "dmixer"
    rate 48000
    channels 6
    bitrate 448
    format S16_LE
}

pcm.dmixer {
    type dmix
    ipc_key 123789
    ipc_key_add_uid true
    slave {
        pcm "hw:0,1"
    }
}

pcm.ac3_stereo {
    type route
    slave.pcm "ac3_51"
    slave.channels 6
    ttable.0.0 1
    ttable.1.1 1
    ttable.0.2 1
    ttable.1.3 1
    ttable.0.4 0.5
    ttable.1.4 0.5
    ttable.0.5 0.5
    ttable.1.5 0.5
}

pcm.!default {
    type empty
    slave {
        pcm "ac3_stereo"
    }
}

ctl.!default {
        type hw
        card 0
}

pcm.!surround51 {
    type empty
    slave {
        pcm "ac3_51"
    }
}

ctl.!surround51 {
        type hw
        card 0
}
