I have a big prob with the oss 3.9.7 driver for my C-Media 8738.

The sound is very slow and it's not my specs (cpu 1300mhz....)

There is my encoded mp3 to show to u the sound :

(Right-click save as)

Audio file contain:

My original mix reading on Windows XP (length: 50 sec) followed by 3 beep then my orginal mix reading by oss linux driver.

How i do that?
Simple, i use a professional digital recorder and i plug in to my soundcard and i just record the output!!!

1) Try buffering
2) Try adding some options to the sound module if it has any
3) Type ps aux and look for artsd or esd. Turn them off by issuing kill -9 PID#
4) How does it sound when playing a wav file instead of mp3? MP3 takes more processor time than WAV. Also your sound device is using the processor most of the time.
5) Try using ALSA. You can do some interesting things with ALSA.

In your sound file, bass is distorted. Turn your sound card's volume to about 75%. This should decrease the bass distortion.

Not many modules have special options that you can adjust. Read the documentation that came with your sound modules. It may say something. Its something like
http://www.alsa-project.org/alsa-doc...howto/x719.htm
Its only for ALSA modules.

There are many different kinds of CM8738 sound chipsets. Take a look at ALSA. You will see several different sound devices using it. Each one has its own setup.

You can try changing /dev/rtc to 1024 and chmod it to 666. This will improve other programs like mplayer, xine, etc.
