Hi,

In some ALSA dmix configurations, alsasink produces cracking sound.

Only alsasink behaves as such, other ALSA apps are fine.  Changing the ALSA dmix
configuration with a newer sample one seems to fix the issue.  This looks like a
corner case in alsasink.

This was reported in Debian by 4-5 persons in Debian bugs
http://bugs.debian.org/323447 and http://bugs.debian.org/324163.

These people have the problem on multiple machines, with very different audio
hardware.  Here's a sample problematic asoundrc:


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

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

pcm.dmixer {
        type dmix
        ipc_key 1024
        slave { 
                pcm "hw:0,0"
                period_time 0
                period_size 1024
                buffer_size 4096
                rate 44100
        }
        bindings {
                0 0
                1 1
        }
}

ctl.dmixer {
        type hw
        card 0
}
