Ubuntu 9.04 solves a problem without sound (Realtek sound card)

Just bought a new computer installed on the latest Ubuntu 9.04, finished and found no sound. This gives me a bit of a disappointment with the powerful features of Ubuntu's automatic identification card.

My sound card is Realtek ALC888. There is a bug on the internet, there are some strange ways to solve, try a lot of unsuccessful. After a constant attempt, the personal feeling is that Ubuntu offers a driver that can't be applied to my sound card. So I went to the Internet to check the latest sound card driver.

Luckily, the Realtek website has a Linux driver, so it's down to install. Finally succeed. It seems that the official thing is hard enough. If you have the same problem, don't try to solve the strange solutions on the Internet.

Specifically, you can choose a Linux driver download at [this URL]. Unzip when the download is complete. There is a readme file. Follow the above. Note that running install directly is not successful and needs to be performed in the manual section.

Step 3 D) requires the use of sudo.
Step 3 E) There was an error in the execution and skipped.
Step 4 did not find any of the files in/etc/modules.conf and Conf.modules. However, the following files are available:/etc/modprobe.d/alsa-base.conf. Open with gedit (note that sudo is required) and post it at the end

Note If you are a different type of sound card, you need to modify the end of the third line. The readme is clearly written.

After the reset, the sound finally came back ....
