[Off Topic] sound car

[mk360]

    Hi,

    I'm trying to configure an audio sound card on my ubuntu becouse it was 
detected but sounds really low. I downloaded a driver from the manufacturer, 
but I've some doubts. The thing is on the readme file all instructions are 
for alsa, and I don't know if it is aplicable for the new ubuntu systems 
with pulse. my configurations are for karmic or lucid.

    Here is the readme file:
The source code copy from www.alsa-project.org. ver:5.14

This Source Code is from www.alsa-project.org.

For OS installation, please remember add the Development tool kit.

For driver installation, please follow below steps.

Automatic install: (Recommend RedHat distribution)

execute

./install

Note: Ubuntu OS, please use manual install.

Run commands need to add sudo at first words.

Manual install:

Step 1. unzip source code

tar xfvj alsa-driver-1.0.xx.tar.bz2

Step 2. Turn on sound support from kernel config

(soundcore module, default turn on)

Step 3. Complied source code

a. cd alsa-driver-1.0.xx

b. ./configure (--with-cards=hda-intel)<= for HDA options

c. make

d. make install

e. alsaconf

Step 4. Edit your /etc/modules.conf or conf.modules depending on the 
distribution

(Please refer to the attached modules.conf)


snd-xxxx is the card ID.

Copy and paste this to the bottom of your /etc/modules.conf or 
/etc/modprobe.conf file.

# ALSA portion

alias char-major-116 snd

alias snd-card-0 snd-xxxx

# OSS/Free portion

alias char-major-14 soundcore

alias sound-slot-0 snd-card-0

# card #1

alias sound-service-0-0 snd-mixer-oss

alias sound-service-0-1 snd-seq-oss

alias sound-service-0-3 snd-pcm-oss

Step 5. reboot your machine

Step 6. Use the alsamixer the disable mute (All audio line default is mute)

Note: 1. The most detail information, can refer the 
alsa-kernel/Documenttation/ALSA-Configuration.txt in the azx-021705.tar.bz2.

2. Kernel Version must be 2.6 or later.

3. All mixer channels are muted by default. You must use a native

or OSS mixer program to unmute appropriate channels.

4. If can not compile the source code, try to rename the 
/usr/src/linux-2.x -> /usr/src/linux.

5. The driver added to support the SPDIF functoin.

6. a. You can download the alsa-lib-1.0.x and alsa-utils-1.0.x form the 
www.alsa-project.org, then unzip and install them.

b. Suggest use "alsamixer" to control mixer function.

c. Used "alsaconf" can autodetect which drive you need to install (step 4).

7. SUSE Distribution must install the ncurses package.
