AlsaSound System doesn't work after installation

[rayen16]

Hi,

I followed this guide: http://www.gentoo.org/doc/en/alsa-guide.xml to install ALSA, the soundsystem doesn't really seem to work

I have compiled my kernel with 'genkernel'

bash-2.05b# lspci | grep -i audio
0000:02:0a.0 Multimedia audio controller: Creative Labs SB Live! EMU10k1 (rev 07)

/etc/modules.autoload.d/kernel-2.6 = empty
my /etc/make.conf
# These settings were set by the catalyst build script that automatically built this stage
# Please consult /etc/make.conf.example for a more detailed example

CFLAGS="-march=pentium4 -O2 -pipe -fomit-frame-pointer"
CHOST="i686-pc-linux-gnu"
CXXFLAGS="${CFLAGS}"
ALSA_CARDS="emu10k1"
USE="-oss"

[adaptr]

You have aliased the /dev/nodes twice - you shouldn't have to do this at all.
And you really do need USE="oss", or the /dev/dsp link won't exist.

I changed the -oss to oss : /etc/make.conf
# These settings were set by the catalyst build script that automatically built this stage
# Please consult /etc/make.conf.example for a more detailed example
#CFLAGS="-O2 -march=pentium4 -fomit-frame-pointer"

CXXFLAGS="${CFLAGS}"
ALSA_CARDS="emu10k1"
USE="oss"

ok so that explains why MPlayer showed the /dev/dsp error

ok I removed the 'double' lines this is how my /etc/modules.d/alsa looks like now:
