documentation – DragonFly BSD Handbook, the FreeBSD Handbook, guide is my contribution to the BSD ecosystem, a humble attempt at. DragonFlyBSD will run on the newer Dell XPS’s such as the , with a little work. There are two major issues with this laptop. The first is that. ,7 +17,7 @@ standard build targets and compile-time flags. Building a kernel is a somewhat involved process. Documentation. for it can be found at.

The line for this driver is:. This example loads the driver for a built-in audio chipset based on the Intel specification:. FreeBSD supports a wide variety of sound cards. This bsv device is sometimes enumerated before the sound card meaning that the sound card will not be used as the default playback device.
If it recommends a method or practice that is outdated, that section should be removed and descriptions of modern methods and practices should be added in their place. All FreeBSD documents are available for download at https: 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:. This command should produce some noise, confirming that the sound card is working.
The next section lists some common problems and their solutions. The number of virtual channels for a device cannot be changed while it is in use. Type fstat grep dsp to check if another application is holding the device open. If a particular portion of the chapter cannot be tested by the student, they should make a note of this in the updated version of the document and link from new document to the old document in that particular spot, pointing out the possible solution or method in the old handbook.
This example is from a system with a built-in Conexant CX chipset:. The output will vary depending upon the sound card. The easiest way is to load a handboo, module for the sound card with kldload 8. Content in the old version is not necessarily out of date, it just has not been verified as being up-to-date, which is necessary for it drgonfly be added to the new handbook.
The output looks something like this:. It is often desirable to have multiple sources of sound that are able to play simultaneously. Check the supported audio devices list of the Hardware Notes to see if the card is supported and which FreeBSD driver it uses.
On the DragonFly website there are 2 versions of the handbook, an old and new version. The settings shown above are the hqndbook. Before beginning the configuration, determine the model of the sound card and the chip it uses. This task entails reviewing the entire handbook chapter in question and verifying that all information contained in that chapter is correct.

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. Noteworthy troublemakers are esound and KDE ‘s sound support. 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. After loading the required module or rebooting into the custom kernel, the sound card should be detected.
This example allocates four virtual channels, which is a practical number for everyday use. Refer to pcm 4 for more information. Modern graphics cards often come with their own sound driver for use with HDMI. The default values for the different mixer channels are hardcoded in the source code of the pcm 4 driver.

For this card, the following lines must be added to the kernel configuration file:. This section is for users who prefer to statically compile in support for the sound card in a custom kernel. Audio CD s have specialized encodings which means that they should not be mounted using mount 8.

When using a custom kernel to provide sound support, make sure that the audio framework driver exists in the custom kernel configuration file:. If all goes well, the sound card should now work in FreeBSD.
If no pcm devices are listed, double-check that the correct device hnadbook was loaded or compiled into the kernel.
Enhanced by Marc Fonvieille. This will set the volume channel to a default value of 50 when the pcm 4 module is loaded. In some cases, the Dragofly or other settings may need to be changed to match the card.
