Procedure 5.1. Configuring Sound Cards¶
If you have added a new sound card or YaST could not automatically configure an existing sound card, follow the steps below. For configuring a new sound card, you need to know your sound card vendor and model. If in doubt, refer to your sound card documentation for the required information. For a reference list of sound cards supported by ALSA with their corresponding sound modules, see http://www.alsa-project.org/main/index.php/Matrix:Main.
During configuration, you can choose between the following setup options:
You are not required to go through any of the further configuration steps—the sound card is configured automatically. You can set the volume or any options you want to change later.
Allows you to adjust the output volume and play a test sound during the configuration.
For experts only. Allows you to customize all parameters of the sound card.

For everyday use and fine-tuning of sound options, use the mixer applet provided by your desktop or the alsasound command line tool. | |
For playback of MIDI files, select +.
When a supported sound card is detected (like a Creative
Soundblaster Live, Audigy or
AWE sound card), you can also install SoundFonts for
playback of MIDI files:
Insert the original driver CD-ROM into your CD or DVD drive.
Select + to copy SF2 SoundFonts™ to
your hard disk. The SoundFonts are saved in the directory
/usr/share/sfbank/creative/.
If you have configured more than one sound card in your system you can
adjust the order of your sound cards. To set a sound card as primary
device, select the sound card in the and click +. The sound
device with index 0 is the default device and thus
used by the system and the applications.
Per default, SUSE Linux Enterprise Desktop uses the PulseAudio sound system. It is an abstraction layer that helps to mix multiple audio streams, bypassing any restrictions the hardware may have. To enable or disable the PulseAudio sound system, click +. If enabled, PulseAudio daemon is used to play sounds. Disable in case you want to use something else system-wide.
The volume and configuration of all sound cards are saved when you click
and leave the YaST sound module. The mixer
settings are saved to the file /etc/asound.state. The
ALSA configuration data is appended to the end of the file
/etc/modprobe.d/sound and written to
/etc/sysconfig/sound.
YaST can be used to configure a local printer that is directly connected to your machine (normally with USB or parallel port) and to set up printing with network printers. It is also possible to share printers over the network. Further information about printing (general information, technical details, and troubleshooting) is available in Chapter 13, Printer Operation (↑Administration Guide).
In YaST, click + to start the printer module. By default it opens in the view, displaying a list of all printers that are available and configured. This is especially useful when having access to a lot of printers via the network. From here you can also and configure local printers.
Usually a local USB printer is automatically detected. There are two possible reasons why a USB printer is not automatically detected:
The USB printer is switched off.
The communication between printer and computer is not possible. Check the cable and the plugs to make sure that the printer is properly connected. If this is the case, the problem may not be printer-related, but rather a USB related problem.
Configuring a printer is basically a three-step process. First specify the connection type, then choose a driver, and name the printing queue for this setup.
For many printer models, several drivers are available. When configuring
the printer, YaST defaults to the one marked
recommended as a general rule. Normally it is not
necessary to change the driver—the recommended
one should produce the best results. However, if you want a color printer
to print only in black and white, it is most convenient to use a driver
that does not support color printing, for example. If you experience
performance problems with a PostScript printer when printing graphics, it
may help to switch from a PostScript driver to a PCL driver (provided
your printer understands PCL).
If no driver for your printer is listed, you can try to select a generic driver with an appropriate standard language from the list. Refer to your printer's documentation to find out which language (the set of commands controlling the printer) your printer understands. If this does not work, refer to Section 5.5.1.1, “Adding Drivers with YaST” for another possible solution.
A printer is never used directly, but always through a print queue. This ensures that simultaneous jobs can be queued and processed one after the other. Each printer queue is assigned to a specific driver, and a printer can have multiple queues. This makes it possible to set up a second queue on a color printer that prints black and white only, for example. Refer to Section “The Workflow of the Printing System” (Chapter 13, Printer Operation, ↑Administration Guide) for more information about print queues.
Procedure 5.3. Adding a New Local Printer¶
Start the YaST printer module with +
Click in the screen
If your printer is already listed under Specify the
Connection, proceed with the next step. Otherwise, try to
or start the .
Enter the vendor name and the model name into the input box under
Find and Assign a Driver and click .
Choose the driver marked as recommended that best matches your printer. If no suitable drivers is displayed
check your search term
broaden your search by clicking
add a driver as described in Section 5.5.1.1, “Adding Drivers with YaST”
Specify the Default paper size
Enter a unique name for the printer queue in the field.
The printer is now configured with the default settings and ready to use. Click to return to the view. The newly configured printer is now visible in the printers list.
If no suitable driver is available in the dialog when adding a new printer, no PPD (PostScript Printer Description, commonly referred to as “printer driver”) file for your model is available. For more information about PPD files, refer to Section “Installing the Software” (Chapter 13, Printer Operation, ↑Administration Guide).
Get PPD files directly from your printer vendor or from the driver CD of a PostScript printer. For details, see Section “No Suitable PPD File Available for a PostScript Printer” (Chapter 13, Printer Operation, ↑Administration Guide). Conversely, you can also find PPD files at http://www.linuxfoundation.org/en/OpenPrinting/, the “OpenPrinting.org printer database”. When downloading PPD files from OpenPrinting.org, keep in mind that it always shows the latest Linux support status, which is not necessarily met by SUSE Linux Enterprise Desktop.
Procedure 5.4. Adding a PPD file
Start the YaST printer module with +
Click in the screen
Click in the Assign
Driver section
Enter the full path to the PPD file into the input box under
Make a Printer Description File Available or choose
the file from a dialog box by clicking on
Click to return to the Add New Printer
Configuration screen.
In order to directly use this PPD file, proceed as described in Procedure 5.3, “Adding a New Local Printer”. Otherwise, click .
By editing an existing configuration for a local printer you can not only change basic settings as connection type and driver, but also adjust the default settings for paper size, resolution, media source, etc. You can change the identifier of the printer by altering the printer descriptions.
Procedure 5.5. Editing a Local Printer
Start the YaST printer module with +
In the screen, choose a local printer from the list and click .
Change the connection type or the driver as described in Procedure 5.3, “Adding a New Local Printer”. This should only be necessary in case you have problems with the current configuration.
Make this printer the default by checking .
Adjust the default settings by clicking . To change a setting, expand the list of
options by clicking the relative + sign. Change the
default by clicking on an option. Apply your changes by clicking
Network printers are not detected automatically. They must be configured manually using the YaST printer module. Depending on your network setup, you can print to a print server (CUPS, LPD, SMB, or IPX) or directly to a network printer (preferably via TCP). Access the configuration view for network printing by choosing from the left pane in the YaST printer module.
In a Linux environment CUPS is usually used to print via the network. The simplest setup is to only print via a single CUPS server which can directly be accessed by all clients. Printing via more than one CUPS server requires a running local CUPS daemon that communicates with the remote CUPS servers.
Procedure 5.6. Printing via a Single CUPS server
Start the YaST printer module with +
Launch the screen from the left pane.
Check and specify the name or IP address of the server.
Click to make sure you have chosen the correct name/IP address.
Click OK to return to the screen. All printers available via the CUPS server are now listed.
Procedure 5.7. Printing via multiple CUPS servers
Start the YaST printer module with +
Launch the screen from the left pane.
Check
Specify which servers to use under General
Settings. You may accept connections from all networks
available, from the local network, or from specific hosts. If you
choose the latter option, you need to specify the hostnames or IP
addresses, as well.
Confirm by clicking and then when asked to start a local CUPS server. After the server has started you will return to the screen. Click to see the printers detected by now. Click this button again, in case more printer are to be available.
If your network offers print services via print servers other than CUPS, start the YaST printer module with + and launch the screen from the left pane. Start the and choose the appropriate type. Ask your network administrator for details on configuring a network printer in your environment.
Printers managed by a local CUPS daemon can be shared over the network and so turn your machine into a CUPS server. Usually you share a printer by enabling CUPS' so-called “browsing mode”. If browsing is enabled, the local printer queues are made available on the network for listening to remote CUPS daemons. It is also possible to set up a dedicated CUPS server that manages all printing queues and can directly be accessed by remote clients. In this case it is not necessary to enable browsing.
Procedure 5.8. Sharing Printers
Start the YaST printer module with +
Launch the screen from the left pane.
Select . For more detailed configuration, additional options are available:
Check and enable browsing mode by also checking .
the network interface to be used by the CUPS server. If you want to share your printers via specified network interfaces, add those in the input box below.
In case you like to restrict access to your CUPS server to certain networks or IP addresses, specify these via the two input boxes.
Click to restart the CUPS server and return to the screen.
Regarding CUPS and firewall settings, see http://en.opensuse.org/SDB:CUPS_and_SANE_Firewall_settings.
You can configure a USB or SCSI scanner with YaST. The
sane-backends package contains
hardware drivers and other essentials needed to use a scanner. Scanners
connected to a parallel port cannot be configured with YaST. If you own
a HP All-In-One device, see
Section 5.6.1, “Configuring an HP All-In-One Device”, instructions on how to
configure a network scanner are available at
Section 5.6.3, “Scanning over the Network”.
Procedure 5.9. Configuring a USB or SCSI Scanner¶
Connect your USB or SCSI scanner to your computer and turn it on.
Start YaST and select +. YaST builds the scanner database and tries to detect your scanner model automatically.
If a USB or SCSI scanner is not properly detected, try +.
To activate the scanner select it from the list of detected scanners and click .
Choose your model form the list and click and .
Use + to make sure you have chosen the correct driver.
Leave the configuration screen with .
An HP All-In-One device can be configured with YaST even if it is connected to the parallel port or is made available via the network. If you own a USB HP All-In-One device, start configuring as described in Procedure 5.9, “Configuring a USB or SCSI Scanner”. If it is detected properly and the succeeds, it is ready to use.
If your USB device is not properly detected, or your HP All-In-One device is connected to the parallel port or the network, run the HP Device Manager:
Start YaST and select +. YaST loads the scanner database.
Start the HP Device Manager with + and follow the on-screen instructions. After having finished the HP Device Manager, the YaST scanner module automatically restarts the auto detection.
