Maybe more than one applications are trying to dump some sounds and your
sound card supports only on stream at the time.
You could make a dmix plugin (software mixing) the default then
in /etc/asound.conf with something like:
pcm.dmixed {
type dmix
ipc_key 1021 # must be unique!
slave {
pcm "hw:0,0" # The sound card
period_time 0
period_size 1024
buffer_size 8192
rate 48000
}
}
pcm.!default {
type plug
slave.pcm "dmixed"
}
