Package: alsa-utils
Version: 1.0.9a-4
Severity: important

After an upgrade today, the dmix plugin stopped working.

    $ mocp 	# or any other program trying to use alsa
    ALSA lib pcm_direct.c:812:(snd_pcm_direct_initialize_slave) requested or auto-format is not available
    ALSA lib pcm_dmix.c:831:(snd_pcm_dmix_open) unable to initialize slave

My ~/.asoundrc is the example configuration for using dmix with the
ICE1712 chip (found e.g. at http://alsa.opensrc.org/index.php?page=DmixPlugin).

# cat ~/.asoundrc
# our ICE1712 dmix:
pcm.ossmix {
    type dmix
    ipc_key 1024
    slave {
    pcm "hw:0,0"
        period_time 0
        period_size 1024
        buffer_size 4096 # buffer size < 6653, but pow(x, 2)
        rate 44100 # we want to play CDs only
    bindings {
        0 0
        1 1
# Everything shall be dmixed, so redefine "default":
pcm.!default {
    type plug
    slave.pcm "ossmix"
# OSS via aoss should d(mix)stroyed:
pcm.dsp0 {
    type plug
    slave.pcm "ossmix"
ctl.mixer0 {
    type hw
    card 0
