The output will vary depending upon the sound card. If nopcm devices are listed, double-check that the correct device driver was loaded or compiled into the kernel. The next section lists some common problems and their solutions.
In my case, I don’t ever intend to use my video card’s HDMI audio output, so I left it un-configured. It has the greatest likelihood of helping a user if they do not deviate from the nominal openSUSE packaged drivers; desktop and kernel. That is, if one installs a custom kernel or updates to a factory KDE version , or applies a manufacturer-provided sound driver, there is an increased probability that this guide will not be of help.
However, this method doesn’t delete the driver files from your hard drive. A more thorough approach may be available via the Control Panel’s ‘Add or Remove Programs’ applet. Many recent audio interfaces provide a dedicated uninstall option as part of their setup application. Annoyingly, though, even running such an uninstall routine may leave behind various files . Drivers act as the glue between hardware devices and operating systems such as Windows, Mac OS and Linux.
ALSA — A Linux kernel component providing device drivers and lowest-level support for audio hardware. Generally, installing a newer version of a driver for existing hardware is easier than getting rid of those related to hardware you are about to or have already removed. Nevertheless, many musicians run into problems while updating audio-interface Samsung drivers drivers and, once again, thoroughly removing the old ones first nearly always results in fewer ‘issues’ later on.
However, if the problem persists in your live session, it’s more likely that a hardware problem is the cause of your sound issues. And choosing a different Linux distro for your live session can help you determine whether your problem is distro-specific. Using the "automated" realtek official driver installation leaves you to a no-sound and no hardware sound support.
You can also run a live session of either Ubuntu or Linux Mint to troubleshoot the problem. Download the ISO of the desired version of Ubuntu or Linux Mint, then install it on a USB flash drive or DVD . If running the live session solves your audio problem, then it’s most likely a software problem.
Most hardware devices you use with your PC require drivers — but what happens to them and their associated files when you change the hardware or update to new drivers? Unfortunately, they hang about in various locations, cluttering your hard drive and storing up problems for the future. We explain how to make a clean sweep and get rid of them once and for all. Previously one would choose the settings to update windows and device drivers. However, after the release of Windows 10, most updates are forced on your system.
If all else fails, contact the manufacturer or post a request on an associated support forum to find the best approach for a thorough uninstall. The simplest way to uninstall device drivers before removing the hardware from your PC is to open Device Manager, right-click on the device in question, and then select the Uninstall option. You then click on the OK button in the subsequent ‘Confirm Device Removal’ dialogue box and, once the deed is done, power down your PC and remove the hardware.
The very best option is to run a dedicated stand-alone uninstall utility that will completely erase all references to a particular piece of hardware once and for all, before or after you physically remove it. You can even run the latest driver installer utility if it first uninstalls the old drivers and then provides an option to install the new ones.
Once they’ve all been deleted, select your preferred device and click the "Edit" button to configure it. If it was already configured automatically during openSUSE installation, then choosing "Quick automatic setup" in the next window should work fine. Once configured, that device will be at index 0 and at the top of the list. You can choose to leave any other devices un-configured, or you can configure them too in case you ever intend to use them.
