Comment 14 for bug 8107

The workaround I use to use a ~/.asoundrc specifying my second soundcard as the
default. Almost all (polypaudio being a notable exception, see Bug 13407)
programs respect and use the "default" soundcard.

The other issue this doesn't solve is programs still using OSS, and accessing
the dsp devices.

The nice thing about this solution is it's completely user-space.
