With 24 this option disabled, kernel will only claim actually in-use 25 device numbers and opening a missing device will generate only the 26 standard char-major-* aliases. 27 28 The only visible difference is use of additional module aliases 29 and whether OSS sound devices appear multiple times in 30 /proc/devices. sound-slot/service-* module aliases are scheduled 31 to be removed (ie. PRECLAIM won't be available) and this option is 32 to make the transition easier. This option can be overridden 33 during boot using the kernel parameter soundcore.preclaim_oss. 34 35 Disabling this allows alternative OSS implementations. 36 37 If unsure, say Y. 38 39source "sound/oss/dmasound/Kconfig" 40 41if !UML 42 43menuconfig SND 44 tristate "Advanced Linux Sound Architecture" 45 help 46 Say 'Y' or 'M' to enable ALSA (Advanced Linux Sound Architecture), 47 the new base sound system. 48 49 For more information, see <http://www.alsa-project.org/> 50 51if SND 52 53source "sound/core/Kconfig" 54 55source "sound/drivers/Kconfig" 56 57source "sound/isa/Kconfig" 58 59source "sound/pci/Kconfig" 60 61source "sound/hda/Kconfig" 62 63source "sound/ppc/Kconfig" 64 65source "sound/ac97/Kconfig" 66 67source "sound/aoa/Kconfig" 68 69source "sound/arm/Kconfig" 70 71source "sound/atmel/Kconfig" 72 73source "sound/spi/Kconfig" 74 75source "sound/mips/Kconfig" 76 77source "sound/sh/Kconfig" 78 79# the following will depend on the order of config. 80# here assuming USB is defined before ALSA 81source "sound/usb/Kconfig" 82 83source "sound/firewire/Kconfig" 84 85# the following will depend on the order of config. 86# here assuming PCMCIA is defined before ALSA 87source "sound/pcmcia/Kconfig" 88 89source "sound/sparc/Kconfig" 90 91source "sound/parisc/Kconfig" 92 93source "sound/soc/Kconfig" 94 95source "sound/x86/Kconfig" 96 97source "sound/synth/Kconfig" 98 99endif # SND 100 101endif # !UML 102 103endif # SOUND 104 105# AC97_BUS is used from both sound and ucb1400 106config AC97_BUS 107 tristate 108 help 109 This is used to avoid config and link hard dependencies between the 110 sound subsystem and other function drivers completely unrelated to 111 sound although they're sharing the AC97 bus.
