# SPDX-License-Identifier: GPL-2.0-only menuconfig SOUND tristate "Sound card support" depends on HAS_IOMEM help If you have a sound card in your computer, i.e. if it can say more than an occasional beep, say Y. if SOUND config SOUND_OSS_CORE bool default n config SOUND_OSS_CORE_PRECLAIM bool "Preclaim OSS device numbers" depends on SOUND_OSS_CORE default y help With this option enabled, the kernel will claim all OSS device numbers if any OSS support (native or emulation) is enabled whether the respective module is loaded or not and try to load the appropriate module using sound-slot/service-* and char-major-* module aliases when one of the device numbers is opened. With this option disabled, kernel will only claim actually in-use device numbers and opening a missing device will generate only the standard char-major-* aliases. The only visible difference is use of additional module aliases and whether OSS sound devices appear multiple times in /proc/devices. sound-slot/service-* module aliases are scheduled to be removed (ie. PRECLAIM won't be available) and this option is to make the transition easier. This option can be overridden during boot using the kernel parameter soundcore.preclaim_oss. Disabling this allows alternative OSS implementations. If unsure, say Y. source "sound/oss/dmasound/Kconfig" if !UML menuconfig SND tristate "Advanced Linux Sound Architecture" help Say 'Y' or 'M' to enable ALSA (Advanced Linux Sound Architecture), the new base sound system.

Concerned drivers should "select" this.
