[gentoo-user] ALSA: All modules loaded, mixer unmuted, still no sound

["Ducky Z." <duckyhatezchat@gmail.com>]

Hello,

The sound card works fine with Ubuntu in my other partition. I've
followed Gentoo's Alsa Guide and currently with kernel modules. But no
sound comes out when I play music or any other things.

The 'lspci' for my card is:

00:1e.2 Multimedia audio controller: Intel Corporation
82801FB/FBM/FR/FW/FRW (ICH6 Family) AC'97 Audio Controller (rev 04)
	Subsystem: Toshiba America Info Systems Unknown device ff10
	Flags: bus master, medium devsel, latency 0, IRQ 10
	I/O ports at e100 [size=256]
	I/O ports at e200 [size=64]
	Memory at d0180000 (32-bit, non-prefetchable) [size=512]
	Memory at d0180200 (32-bit, non-prefetchable) [size=256]
	Capabilities: [50] Power Management version 2

The 'lsmod' for the OS is:

Some dmesg'es related to my card:
ACPI: PCI Interrupt 0000:00:1e.2[A] -> Link [LNKB] -> GSI 10 (level,
low) -> IRQ 10
PCI: Setting latency timer of device 0000:00:1e.2 to 64

My alsaconf generated:

When I play an mp3 file with mpg321, the first two lines show:
ALSA lib pcm_direct.c:900: (snd_pcm_direct_initialize_slave) unable to
install hw params
ALSA lib pcm_dmix.c:831: (snd_pcm_dmix_open) unable to initialize slave

There's no sound when #cat /dev/random > /dev/dsp

My /proc/asound/cards:
 0 [ICH6           ]: ICH4 - Intel ICH6
                      Intel ICH6 with AD1981B at 0xd0180000, irq 10


My 'uname -a':
Linux rolling-machine 2.6.15-nitro3 #3 PREEMPT Sun Feb 26 13:23:00 MMT

I've  searched in forums, and haven't found any solution yet. All
channels are unmuted and set to full. I hope some could help me out.

Thanks,
DZ.
