This is an ubuntu breezy ppc distribution, and it seems that the package
is called libasound2, and it is based on alsa-lib 1.0.9-2.

Stracing the aplay process shows that dmix.conf is being read:

	defiant:~ 20 > strace -eopen aplay wav/slow_20spindle_20motor.wav
	open("/etc/ld.so.cache", O_RDONLY)      = 3
	open("/usr/lib/libasound.so.2", O_RDONLY) = 3
	open("/lib/libm.so.6", O_RDONLY)        = 3
	open("/lib/libdl.so.2", O_RDONLY)       = 3
	open("/lib/libpthread.so.0", O_RDONLY)  = 3
	open("/lib/libc.so.6", O_RDONLY)        = 3
	open("/usr/share/alsa/alsa.conf", O_RDONLY) = 3
	open("/usr/share/alsa/cards/aliases.conf", O_RDONLY) = 3
	open("/usr/share/alsa/pcm/default.conf", O_RDONLY) = 4
	open("/usr/share/alsa/pcm/dmix.conf", O_RDONLY) = 4
	open("/usr/share/alsa/pcm/dsnoop.conf", O_RDONLY) = 4
	open("/dev/snd/controlC0", O_RDONLY)    = 3
	open("/dev/snd/controlC0", O_RDONLY)    = 3
	open("/dev/snd/controlC0", O_RDWR)      = 3
	open("/dev/snd/controlC1", O_RDONLY)    = -1 ENOENT (No such file or directory)
	open("/dev/aloadC1", O_RDONLY)          = -1 ENOENT (No such file or directory)
	[...]

I suppose I could test with 1.0.11rc2 if it does make sense to.
