With 25 this option disabled, kernel will only claim actually in-use 26 device numbers and opening a missing device will generate only the 27 standard char-major-* aliases. 28 29 The only visible difference is use of additional module aliases 30 and whether OSS sound devices appear multiple times in 31 /proc/devices. sound-slot/service-* module aliases are scheduled 32 to be removed (ie. PRECLAIM won't be available) and this option is 33 to make the transition easier. This option can be overridden 34 during boot using the kernel parameter soundcore.preclaim_oss. 35 36 Disabling this allows alternative OSS implementations. 37 38 If unsure, say Y. 39 40source "sound/oss/dmasound/Kconfig" 41 42if !UML 43 44menuconfig SND 45 tristate "Advanced Linux Sound Architecture" 46 help 47 Say 'Y' or 'M' to enable ALSA (Advanced Linux Sound Architecture), 48 the new base sound system. 49 50 For more information, see <http://www.alsa-project.org/> 51 52if SND 53 54source "sound/core/Kconfig" 55 56source "sound/drivers/Kconfig" 57 58source "sound/isa/Kconfig" 59 60source "sound/pci/Kconfig" 61 62source "sound/hda/Kconfig" 63 64source "sound/ppc/Kconfig" 65 66source "sound/ac97/Kconfig" 67 68source "sound/aoa/Kconfig" 69 70source "sound/arm/Kconfig" 71 72source "sound/atmel/Kconfig" 73 74source "sound/spi/Kconfig" 75 76source "sound/mips/Kconfig" 77 78source "sound/sh/Kconfig" 79 80# the following will depend on the order of config. 81# here assuming USB is defined before ALSA 82source "sound/usb/Kconfig" 83 84source "sound/firewire/Kconfig" 85 86# the following will depend on the order of config. 87# here assuming PCMCIA is defined before ALSA 88source "sound/pcmcia/Kconfig" 89 90source "sound/sparc/Kconfig" 91 92source "sound/parisc/Kconfig" 93 94source "sound/soc/Kconfig" 95 96source "sound/x86/Kconfig" 97 98source "sound/synth/Kconfig" 99 100source "sound/xen/Kconfig" 101 102source "sound/virtio/Kconfig" 103 104endif # SND 105 106endif # !UML 107 108endif # SOUND 109 110# AC97_BUS is used from both sound and ucb1400 111config AC97_BUS 112 tristate 113 help 114 This is used to avoid config and link hard dependencies between the 115 sound subsystem and other function drivers completely unrelated to 116 sound although they're sharing the AC97 bus.
