Re: [linrad] ALSA vs OSS ?

[Edson Pereira <edson@xxxxxxxxxxxxx>]

This is what I have in the machines I have installed alsa:

Distro:  Red Hat Linux release 7.2 (Enigma)
CC:      gcc version 2.96 20000731 (Red Hat Linux 7.2 2.96-108.7.2)
Kernel:  Linux 2.4.19 (compiled from sources)
Sound:   SoundBlaster Live (EMU10K1 Chipset)
Driver:  ALSA 0.9.0beta12
LinRad:  lir00-48
Remarks: SB Live's mixer has too many controls and options, making the 
         card configuration quite tedious and complex.

Distro:  Red Hat Linux release 8.0 (Psyche) 
CC:      gcc version 3.2 20020903 (Red Hat Linux 8.0 3.2-7) 
Kernel:  Linux 2.4.18 (RedHat's original) 
Sound:   C-Media compatible (CMI9738 Chipset) 
Driver:  ALSA 0.9.0rc6 
LinRad:  lir00-48 
Remarks: The OSS Free driver did not work with linrad (API problems). The
ALSA driver worked just fine. This is a 1000 Yen (US$8) soundcard very
popular in Japan now days. Good sound quality and low noise.

I did not have problems installing ALSA since version 0.6. The steps I
used to install version 0.9rc6 were:

0. Have the Linux kernel development package (headers) installed.
1. Download ALSA drivers, libs, utils, tools, and oss lib.

2. tar -zxvf alsa-driver
3. ./configure; make
4. as root, make install
5. as root, ./snddevices

6. tar -zxvf alsa-libs
7. ./configure; make
8. as root, make install

9. tar -zxvf alsa-utils
10. ./configure; make
11. as root, make install

12. tar -zxvf alsa-tools
13. ./configure; make
14. as root, make install

15. tar -zxvf alsa-oss
16. ./configure; make
17. as root, make install

To load the drivers by hand:

As root, 

/sbin/modprobe your_sound_driver_module_name
/sbin/modprobe snd-pcm-oss

The OSS driver must be loaded separately.

You can check the loaded modules with the command:

/sbin/lsmod

To have the modules loaded automatically the next time you boot Linux,
edit /etc/modules.conf and insert the appropriate lines. Instructions on
how to do this depends on the type of soundcard and sound driver you have.
The instructions can be found at the ALSA web page.

http://www.alsa-project.org/alsa-doc/

Look for your soundcard and click on the Driver & Docs link.

Hope this helps.
