sound on VAIO PCG-FR215S

hello, this is my post, so if i forget some important facts please apology me.
i've installed debian 3.0r on my vaio VAIO PCG-FR215S, right now i'm stuck trying to configure the sound card. the sound card is a

00:04.0 Multimedia audio controller: Acer Laboratories Inc. [ALi] M5451 PCI South Bridge Audio (rev 02)
Subsystem: Sony Corporation: Unknown device 8158
Flags: bus master, medium devsel, latency 64, IRQ 11
I/O ports at 8800 [size=256]
Memory at e0401000 (32-bit, non-prefetchable) [size=4K]
Capabilities: [dc] Power Management version 2

I've installed alsa driver (ali M5452) and alsa lib along with alsa utils. it seems like that the modules are correclty loaded; in fact lsmod tells:

Module Size Used by Not tainted
snd-pcm-oss 36164 0 (autoclean)
snd-mixer-oss 10912 1 (autoclean) [snd-pcm-oss]
snd-ali5451 11492 1 (autoclean)
snd-ac97-codec 33936 0 (autoclean) [snd-ali5451]
snd-pcm 57920 0 (autoclean) [snd-pcm-oss snd-ali5451]
snd-page-alloc 4512 0 (autoclean) [snd-pcm]
snd-timer 13632 0 (autoclean) [snd-pcm]
snd 28224 0 (autoclean) [snd-pcm-oss snd-mixer-oss snd-ali5451 snd-ac97-codec snd-pcm snd-timer]
soundcore 3844 3 (autoclean) [snd]
hostap_cs 48072 1
hostap 67332 0 [hostap_cs]
hostap_crypt 1572 0 [hostap]

the snd modules are automatically loaded when i try to play something
but i get no sound.
any idea?
i've unmuted the channel, i simply rised the volume with alsamixer (is this correct or should i do something else).

I'm using kernel 2.4.19

I've read the the 2.5 kernel has "bult in" alsa, do you think it would be esaier?

I'm using Mandrake 9.1 with Sony PCG-FR215S with "trident" alsa drivers and all works ok.
Could you try the "trident" ("Trident 4DWave DX/NX, SiS 7018 or ALi 5451 PCI Audio Core") driver?
I hope this helps.

Have you tried changing lcd screen brightness??
Thanks (and excuse me for my really poor english)
