This causes a crash in Kerbal Space Program similar to issue #27. A change was made to close issue #27 in alsa-lib 1.2.3. That change did not correct the crash however in 1.2.3 or 1.2.5.1 in my case. This is the noted difference for "aplay -L" between 1.2.3 and 1.2.1: Removing this "default" device entry fixes the issue on this system. You may remove the default device name by editing src/conf/pcm/default.conf and adding under the hint section "omit_noargs true". Unity must be parsing the device name, and with certain device names, if there is no ':' doing something bad, as there is a pattern here on what it trips on. I have no idea how to get them to correct this, so opening the issue here at least for the record if anyone else has an issue with this. Also, I am not sure what triggers "default" to show. I did a survey and 3 out of 5 of my slackware 15.0 systems have it. And 2 do not. Does this have something to do with parsing the system alsa config and the available sound devices in the system? I don't define any asound.conf for any of these, so these are almost 100% stock slackware systems, there should otherwise be no difference.
