Check what sound system you're using. I'd recommend using the ALSA system, but it seems like you're using the old deprecated OSS system. If you want to use /dev/dsp as audio output you have to enable "OSS support" in your kernel config. It'll provide the /dev/dsp node.

How is it installed in-kernel(as modules or statically) or alsa-driver? |

the kernel was made by "genkernel all" and the alsa was installed by "emerge alsa". | Quote: | # emerge alsa -p
These are the packages that would be merged, in order:

Do you mean alsa-driver? If yes make | Code: | | USE="oss" emerge alsa-driver |
In /etc/conf.d/alsasound must be ENABLE_OSS_EMUL="yes"
After that you should have created /dev/dsp node. |

means that you do not use alsa-driver but alsa in kernel. So if you want create /dev/dsp node,
you have to enable /dev/dsp support in kernel, see http://www.gentoo.org/doc/en/alsa-guide.xml Code Listing 2.3: Kernel Options for ALSA |
