Don't do it there. Use /etc/asound.conf or $HOME/.asoundrc ... > pcm.default{ > type > file > file > /tmp/pcm.out > } ... and make it pcm.!default { type file slave { pcm null } file "/tmp/pcm.out" } Exactly why you need that slave definition I'm not sure either, but it seems you do. Also note that /tmp/pcm.out will be headerless PCM and is recreated for individual opens. I don't believe there's an append mode or anything (and you'd need to make sure that everyone plays the same format) so not toot sure if this is what you need to have a catch all audio-sink...
