1menuconfig SOUND 2 tristate "Sound card support" 3 depends on HAS_IOMEM 4 help 5 If you have a sound card in your computer, i.e. if it can say more 6 than an occasional beep, say Y. Be sure to have all the information 7 about your sound card and its configuration down (I/O port, 8 interrupt and DMA channel), because you will be asked for it. 9 10 You want to read the Sound-HOWTO, available from 11 <http://www.tldp.org/docs.html#howto>. General information about 12 the modular sound system is contained in the files 13 <file:Documentation/sound/oss/Introduction>. The file 14 <file:Documentation/sound/oss/README.OSS> contains some slightly 15 outdated but still useful information as well. Newer sound 16 driver documentation is found in <file:Documentation/sound/alsa/*>. 17 18 If you have a PnP sound card and you want to configure it at boot 19 time using the ISA PnP tools (read 20 <http://www.roestock.demon.co.uk/isapnptools/>), then you need to 21 compile the sound card support as a module and load that module 22 after the PnP configuration is finished. To do this, choose M here 23 and read <file:Documentation/sound/oss/README.modules>; the module 24 will be called soundcore. 25 26if SOUND 27 28config SOUND_OSS_CORE 29 bool 30 default n 31 32config SOUND_OSS_CORE_PRECLAIM 33 bool "Preclaim OSS device numbers" 34 depends on SOUND_OSS_CORE 35 default y 36 help 37 With this option enabled, the kernel will claim all OSS device 38 numbers if any OSS support (native or emulation) is enabled 39 whether the respective module is loaded or not and try to load the 40 appropriate module using sound-slot/service-* and char-major-* 41 module aliases when one of the device numbers is opened. With 42 this option disabled, kernel will only claim actually in-use 43 device numbers and opening a missing device will generate only the 44 standard char-major-* aliases. 45 46 The only visible difference is use of additional module aliases 47 and whether OSS sound devices appear multiple times in 48 /proc/devices. sound-slot/service-* module aliases are scheduled 49 to be removed (ie. PRECLAIM won't be available) and this option is 50 to make the transition easier. This option can be overridden 51 during boot using the kernel parameter soundcore.preclaim_oss. 52 53 Disabling this allows alternative OSS implementations. 54 55 If unsure, say Y. 56 57source "sound/oss/dmasound/Kconfig" 58 59if !M68K && !UML 60 61menuconfig SND 62 tristate "Advanced Linux Sound Architecture" 63 help 64 Say 'Y' or 'M' to enable ALSA (Advanced Linux Sound Architecture), 65 the new base sound system. 66 67 For more information, see <http://www.alsa-project.org/> 68 69if SND 70 71source "sound/core/Kconfig" 72 73source "sound/drivers/Kconfig" 74 75source "sound/isa/Kconfig" 76 77source "sound/pci/Kconfig" 78 79source "sound/ppc/Kconfig" 80 81source "sound/aoa/Kconfig" 82 83source "sound/arm/Kconfig" 84 85source "sound/atmel/Kconfig" 86 87source "sound/spi/Kconfig" 88 89source "sound/mips/Kconfig" 90 91source "sound/sh/Kconfig" 92 93# the following will depend on the order of config. 94# here assuming USB is defined before ALSA 95source "sound/usb/Kconfig" 96 97source "sound/firewire/Kconfig" 98 99# the following will depend on the order of config. 100# here assuming PCMCIA is defined before ALSA 101source "sound/pcmcia/Kconfig" 102 103source "sound/sparc/Kconfig" 104 105source "sound/parisc/Kconfig" 106 107source "sound/soc/Kconfig" 108 109endif # SND 110 111menuconfig SOUND_PRIME 112 tristate "Open Sound System (DEPRECATED)" 113 select SOUND_OSS_CORE 114 help 115 Say 'Y' or 'M' to enable Open Sound System drivers. 116 117if SOUND_PRIME 118 119source "sound/oss/Kconfig" 120 121endif # SOUND_PRIME 122 123endif # !M68K 124 125endif # SOUND 126 127# AC97_BUS is used from both sound and ucb1400 128config AC97_BUS 129 tristate 130 help 131 This is used to avoid config and link hard dependencies between the 132 sound subsystem and other function drivers completely unrelated to 133 sound although they're sharing the AC97 bus.
