Testing different ' Audio service stations ': System > Personal settings (how do preferences translate on Chinese system?) > Multimedia System selector. Here, you can test different options. I installed 4 different audio workstations myself, but only 1 were working. If you can't play audio with xine or Rhythmbox, you can use XMMS or helix/ RealPlayer, this problem may also occur on your system.

Useful Tips & Tricks (useful tips and tricks)

You can use Aplay to get a list of sound cards set by ALSA

$ aplay-l
Aplay:device_list:200:no soundcards found ...

The following commands can help figure out what sound card (chip set) your have (look for lines that contain ' Multimedia audio con Troller ')

$ lspci-v
$ lspnp-v

Another script used to collect sound card specifications and Drivers is Aadebug (Http://alsa.opensrc.org/index.php?page=aadebug).

About the compatibility of sound cards: Although most sound cards are built to be compatible with SoundBlaster, only a very small portion of the sound card that is sold has enough compatibility to work with the SoundBlaster driver on Linux. Now figure out abound module for you need: it's time to decide which module you need:

Go to http://www.alsa-project.org/alsa-doc/
Query http://www.alsa-project.org/alsa-doc/
Pick the manufacturer, go
Select Manufacturer,
With the "information provided by previous commands it should is easy to find" right module.
With the information left over from previous commands, you can easily find the right module.

The command is used to test whether the module is available on your system (usually available):

$ modinfo [ModuleName]

It will also help you list the appropriate module parameters. For example, some of the ISA's sound cards require you to modprobe through Isapnp=0. It may also require a sound card IRQ and IO, which can be found in the Aadebug output instructions. Now that you have the information you need, start loading the module.

$ sudo modprobe snd_es18xx isapnp=0 port=0x220 mpu_port=0x330 dma1=1 dma2=5 irq=5 fm_port=0x388

If this instruction does not restore you any errors, then we can save this parameter.

$ echo options [Module-name] [module-options] >>/etc/modprobe.d/[module-name]
