 Posted: Wed Aug 24, 2005 9:47 am Post subject: Installing ALSA |
 |
|
I've installed ALSA separately from the kernel, but no /dev/dsp is found. I'm using a 2.6 kernel with udev.
Why is there no /dev/dsp? How do I create it? |

You might still need to load the alsa modules at boot time, also, to properly use alsa, you probably need to install the 'alsa-utils' and 'alsa-lib' packages. These packages come with init.d scripts to setup your sound at boot time.
Sometimes people forget to enable pcm-oss emulation in the kernel. Double check that you have that option enabled to be sure. |

How do I add these scripts into the startup?
When trying to start hotplug, I get this error: | Code: | mount: unknown filesystem type 'usbdevfs'
umount: /proc/bus/usb: not mounted |
Even in the 2.4 kernel, this caused a non-fatal failure in booting. How do I iron this out?
When in Gentoo, I couldn't have ALSA and a kernel sound driver of any sort. Is it different in Lunar? |

1. uncomment the usb-dev filesystem entry in your fstab
2. When you run a 2.4 kernel, you can only run alsa by installing the 'alsa-driver' package. When you run a 2.6 kernel, you should use the kernel modules in the 2.6.x kernel. This is the same as in any distribution. |

Hi, i installed alsa, maybe my experience will help.
first install alsa-lib
second install alsa-driver
and alsa-utils.
when you are installing, a menuconfig (kernel like) will appears, so, if you sound card is listed, just select, if not, select make all drivers (or something like this).
after that, run alsaconfig to detect your sound card. and that all.
after that, you can use mp3blaser to test it.
i'm using a 2.4 kernel with pcm-oss suport and my card is not listed so i build alsa for all cards.
bye.

Actually, in Gentoo I had to install the external ALSA just to get sound working.
I can't install alsa-driver on my 2.6 kernel. The error is: | Code: | | Please, install the package with full kernel sources for your distribution or use --with-kernel=dir option to specify another directory with kernel sources )default is /lib/modules/2.6.12.4/sources/ |
The directory does exist and there are sources in there, so why doesn't it build

The line was already uncommented.
And the NVIDIA driver is "unable to determine the target kernel version".
EDIT: I've managed to install it, and it apparently starts up at boot, but there still is no /dev/dsp. |

| perhaps you didn't build pcm-oss emulation? check your kernel configs. |

but 90% of applications out there still assume oss - meaning you either have to recompile all applications to use alsa, or just make them happy and give them oss (/dev/dsp == oss or oss emulation).
Of course you can't exactly recompile your favorite binaries from a game for instance.... |
