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 40 source "sound/oss/dmasound/Kconfig" 41 42 if !UML 43 44 menuconfig 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 52 if SND 53 54 source "sound/core/Kconfig" 55 56 source "sound/drivers/Kconfig" 57 58 source "sound/isa/Kconfig" 59 60 source "sound/pci/Kconfig" 61 62 source "sound/hda/Kconfig" 63 64 source "sound/ppc/Kconfig" 65 66 source "sound/ac97/Kconfig" 67 68 source "sound/aoa/Kconfig" 69 70 source "sound/arm/Kconfig" 71 72 source "sound/atmel/Kconfig" 73 74 source "sound/spi/Kconfig" 75 76 source "sound/mips/Kconfig" 77 78 source "sound/sh/Kconfig" 79 80 # the following will depend on the order of config. 81 # here assuming USB is defined before ALSA 82 source "sound/usb/Kconfig" 83 84 source "sound/firewire/Kconfig" 85 86 # the following will depend on the order of config. 87 # here assuming PCMCIA is defined before ALSA 88 source "sound/pcmcia/Kconfig" 89 90 source "sound/sparc/Kconfig" 91 92 source "sound/parisc/Kconfig" 93 94 source "sound/soc/Kconfig" 95 96 source "sound/x86/Kconfig" 97 98 source "sound/synth/Kconfig" 99 100 source "sound/xen/Kconfig" 101 102 endif # SND 103 104 endif # !UML 105 106 endif # SOUND 107 108 # AC97_BUS is used from both sound and ucb1400 109 config AC97_BUS 110 tristate 111 help 112 This is used to avoid config and link hard dependencies between the 113 sound subsystem and other function drivers completely unrelated to 114 sound although they're sharing the AC97 bus.
