Google Code-in Organization DragonFly BSD Task doc: Update Chapter 13 of the old handbook

dragknfly This sound device is sometimes enumerated before the sound card meaning that the sound card will not be used as the default playback device. This will allow for the formatting of the section in place to make sure it looks as good as possible and uniform with the other handbook sections. Check the supported audio devices hanxbook of the Hardware Notes to see if the card is supported and which FreeBSD driver it uses.

The line for this driver is:. These handbooks are located at: To continue the example of the built-in audio chipset based on the Intel specification from the previous section, use the following line in the custom kernel configuration file:.

Next, add support for the sound card. FreeBSD supports a wide variety of sound cards.

If it recommends a method or bs that is outdated, that section should be removed and descriptions of modern methods and practices should be added in their place. The default values for the different mixer channels are hardcoded in the source code of the pcm 4 driver.

When using a custom kernel to provide sound support, make sure that the audio framework driver exists in the custom kernel configuration file:. All FreeBSD documents are available for download at https: Before beginning the configuration, determine the model of the sound card and the chip it uses.

Since the pcm module can be loaded independently of the hardware drivers, hw. On the DragonFly website there are 2 versions of the handbook, an old and new version. It is often desirable to have multiple sources of sound that are able to play simultaneously. If no pcm devices are listed, double-check that the correct device driver was loaded or compiled into the kernel. This is a metadriver which loads all of the most common sound drivers and can be used to speed up the search for the correct driver.

Enhanced by Marc Fonvieille. The output will vary depending upon the sound card.

Modern graphics cards often come with their own sound driver for use with HDMI. The easiest way is to load a kernel module for the sound card with kldload 8. The IRQ is set incorrectly. Noteworthy troublemakers are esound and KDE ‘s sound support.

This example is from a system with a built-in Conexant CX chipset:. The student working on this task may create a personal account for themselves on the wiki see the Edit Page link on the top of any page of the DragonFly website and once they believe they are done they may post the chapter within the new handbook. During the boot process, loader 8 reads this file and dragonvly the settings to the kernel.

Contributed by Moses Moore. First, close any programs using the device, such as music handbool or sound daemons. Setting Up the Sound Card. In order to use the sound device, its device driver must be loaded. If it is incorrect it must be updated and made correct.

The student may then make any corrections and follow-up edits in-place as requested by the mentor. To check if this is the case, run dmesg and look for pcm.

This will set the volume channel to a default value of 50 when the pcm 4 module is loaded.

Contributed by Munish Chopra. The next section lists some common problems and their solutions. This section is for users who prefer to statically compile in support for the sound card in a custom kernel. Setting Default Values for Mixer Channels. To confirm, run dmesg grep pcm. In some cases, the IRQ or other settings may need to be changed to match the card.

The settings shown above are the defaults. Content in the old version rdagonfly not necessarily out of date, it just has not been verified as being up-to-date, which is necessary for it to be added to the new handbook.

Configuring a Custom Kernel with Sound Support. In this example, it should be 4.

This task entails reviewing the entire handbook chapter in question and verifying that all information contained in that chapter is correct.
