Linux: farewell to the silent world

Linux: farewell to the silent world-general Linux technology-Linux technology and application information. For more information, see the following. (Author: brilliant and dusty) Today I cannot stand the silence of Linux. I decided to install a driver for the sound card.

Choose system> Management> sound card detection. In the displayed dialog box, you can view many information about the sound card. According to this information, the sound card chip integrated on the motherboard is ALC268, And the IO control is 8280 H (ICH8 Family) HD Audio Controller, which should be integrated into the nanqiao chip. In this case, ALC268 is also a soft sound card. The decoding of the soft sound card is all done by the CPU. Only the ALC268 codec Chip on the main board is used for analog-to-digital conversion. ALC268 adopts a High Definition Audio solution. This audio solution supports multi-channel audio playback with a high quality of up to 24bit/192kHz per channel. At the same time, HD Audio also supports functional driver modules developed by manufacturers, which can provide users with functions such as DVD decoding, multi-Audio stream playback, and support for various 3D Audio APIs. The most practical feature is that the multi-Audio stream Playback Technology of HD Audio can provide automatic identification of plug-in by virtue of its internal interface routing function.

Card selected
Manufacturer: Intel Corporation
Model: 8280 H (ICH8 Family) HD Audio Controller
Module: snd-hda-intel

Default sound card: Intel Corporation 82801 H (ICH 8 Family) HD Audio Controller
Default PCM device: ALC268 Analog

ALSA Driver Version: Driver Version 1.0.15.fc8
ALSA library package: alsa-lib-1.0.15-1.fc8
ALSA Toolkit: alsa-utils-1.0.15-1.fc8

The Advanced Linux Sound Architecture (ALSA) provides audio and MIDI functionality to the Linux operating system. ALSA has the following significant features:

Efficient support for all types of audio interfaces, from consumer soundcards to professional multichannel audio interfaces.
Fully modularized sound drivers.
SMP and thread-safe design.
User space library (alsa-lib) to simplify application programming and provide higher level functionality.
Support for the older oss api, providing binary compatibility for most OSS programs.
ALSA is released under the GPL (GNU General Public license) and the LGPL (GNU Lesser General Public License ).

This ALC268 integrated sound card chip seems to be a relatively new product, so that alsa 1.0.15 drivers do not support it, so I cannot hear any sound from the test, which makes me depressed for a long time, however, I have never been too lazy to complete it. Today, I am suddenly making up my mind to say goodbye to this silent world. It is so late in the morning that I can finally write this article.

Search for keywords such as ALC268 and linux on the Internet, and there are a large number of search results. According to the articles, I also tried to modify some configuration files and restart them again and again. I accidentally saw an article. I decided to adopt the simplest method, and I did not uninstall the previously installed alsa driver.

[Root @ localhost ecy] # rpm-qa | grep alsa
Bluez-utils-alsa-3.20-4.fc8
Alsa-lib-devel-1.0.15-1.fc8
Alsa-lib-1.0.15-1.fc8
Alsa-utils-1.0.15-1.fc8
Alsa-plugins-pulseaudio-1.0.14-5.fc8

Prepare these three files, restart them, and test again to hear the sound, which makes me feel so happy.

Then I downloaded the binary Installation File RealPlayer11GOLD. bin from the official website of RealNetworks. I like binary installation files because the installation process is much simpler than that of source code, and there are no errors. for example, Google Earth for Linuxy is also published in. bin mode. Before installation, you need to use chmod to add executable permissions to the file, and then enter ". /RealPlayer11GOLD. bin, then some personalized options will appear, used to make the appropriate choice according to your favorite.

After the installation is complete, A RealPlayer 11 item is added to "Application> audio and video". Click it to run RealPlayer 11. By default, RealPlayer 11supports .rm,.rmvb,.mp3,.wma,.wmv,.ogg and other audio and video formats. Haha, the world of Feodra core 8 has been filled with wonderful voices, so it is even more vibrant.
