7 | help |
8 | If you have a sound card in your computer, i.e. if it can say more |
9 | than an occasional beep, say Y. Be sure to have all the information |
10 | about your sound card and its configuration down (I/O port, |
11 | interrupt and DMA channel), because you will be asked for it. |
12 | |
13 | You want to read the Sound-HOWTO, available from |
14 | <http://www.tldp.org/docs.html#howto>. General information about |
15 | the modular sound system is contained in the files |
16 | <file:Documentation/sound/oss/Introduction>. The file |
17 | <file:Documentation/sound/oss/README.OSS> contains some slightly |
18 | outdated but still useful information as well. Newer sound |
19 | driver documentation is found in <file:Documentation/sound/alsa/*>. |
20 | |
21 | If you have a PnP sound card and you want to configure it at boot |
22 | time using the ISA PnP tools (read |
23 | <http://www.roestock.demon.co.uk/isapnptools/>), then you need to |
24 | compile the sound card support as a module and load that module |
25 | after the PnP configuration is finished. To do this, choose M here |
26 | and read <file:Documentation/sound/oss/README.modules>; the module |
27 | will be called soundcore. |
28 | |
29 | if SOUND |
30 | |
31 | config SOUND_OSS_CORE |
32 | bool |
33 | default n |
34 | |
35 | config SOUND_OSS_CORE_PRECLAIM |
36 | bool "Preclaim OSS device numbers" |
37 | depends on SOUND_OSS_CORE |
38 | default y |
39 | help |
40 | With this option enabled, the kernel will claim all OSS device |
41 | numbers if any OSS support (native or emulation) is enabled |
42 | whether the respective module is loaded or not and try to load the |
43 | appropriate module using sound-slot/service-* and char-major-* |
44 | module aliases when one of the device numbers is opened. With |
45 | this option disabled, kernel will only claim actually in-use |
46 | device numbers and opening a missing device will generate only the |
47 | standard char-major-* aliases. |
48 | |
49 | The only visible difference is use of additional module aliases |
50 | and whether OSS sound devices appear multiple times in |
51 | /proc/devices. sound-slot/service-* module aliases are scheduled |
52 | to be removed (ie. PRECLAIM won't be available) and this option is |
53 | to make the transition easier. This option can be overridden |
54 | during boot using the kernel parameter soundcore.preclaim_oss. |
55 | |
56 | Disabling this allows alternative OSS implementations. |
57 | |
58 | Please read Documentation/feature-removal-schedule.txt for |
59 | details. |

135 | This is used to avoid config and link hard dependencies between the |
136 | sound subsystem and other function drivers completely unrelated to |
137 | sound although they're sharing the AC97 bus. Concerned drivers |
138 | should "select" this. |
