Thanks.

BTW, is it a hardware or a configuration issue the fact that I'm unable
to mix several alsa streams ?

For example, if I issue two instances of 'aplay foo.wav', the first one
plays the sound while the second one remains stuck in:
	stat64("/usr/share/alsa/alsa.conf", {st_mode=S_IFREG|0644, st_size=7467, ...}) = 0
	open("/dev/snd/controlC0", O_RDONLY)    = 3
	close(3)                                = 0
	open("/dev/snd/controlC0", O_RDWR)      = 3
	ioctl(3, USBDEVFS_CONTROL, 0x7fee2bf8)  = 0
	ioctl(3, UI_DEV_CREATE, 0x7fee2ca0)     = 0
	close(3)                                = 0
	open("/dev/snd/controlC0", O_RDONLY)    = 3
	close(3)                                = 0
	open("/dev/snd/controlC0", O_RDWR)      = 3
	ioctl(3, USBDEVFS_CONTROL, 0x7fee2fa8)  = 0
	ioctl(3, 0x80045532, 0x7fee2fd8)        = 0
	open("/dev/snd/pcmC0D0p", O_RDWR
until the first one ends playing. Only then the second one continues the
execution.

Just in case this is useful:
	# cat /proc/asound/version
	Advanced Linux Sound Architecture Driver Version 1.0.11rc2 (Wed Jan 04 08:57:20 2006 UTC).
	# cat /proc/asound/cards
	 0 [Snapper        ]: PMac Snapper - PowerMac Snapper
	                      PowerMac Snapper (Dev 0) Sub-frame 0
	# cat /proc/asound/devices
	  0: [ 0]   : control
	  1:        : sequencer
	 16: [ 0- 0]: digital audio playback
	 24: [ 0- 0]: digital audio capture
	 33:        : timer
	# cat /proc/asound/pcm
	00-00: PMac Snapper : PowerMac Snapper : playback 1 : capture 1
