2593 The ALSA drivers can be loaded automatically 2517 The ALSA drivers can be loaded automatically on demand by defining
2594 module aliases. The string ``snd-card-%1`` i 2518 module aliases. The string ``snd-card-%1`` is requested for ALSA native
2595 devices where ``%i`` is sound card number fro 2519 devices where ``%i`` is sound card number from zero to seven.
2596 2520
2597 To auto-load an ALSA driver for OSS services, 2521 To auto-load an ALSA driver for OSS services, define the string
2598 ``sound-slot-%i`` where ``%i`` means the slot 2522 ``sound-slot-%i`` where ``%i`` means the slot number for OSS, which
2599 corresponds to the card index of ALSA. Usual 2523 corresponds to the card index of ALSA. Usually, define this
2600 as the same card module. 2524 as the same card module.

2609 2533
2610 The available number of auto-loaded sound car 2534 The available number of auto-loaded sound cards depends on the module
2611 option ``cards_limit`` of snd module. As def 2535 option ``cards_limit`` of snd module. As default it's set to 1.
2612 To enable the auto-loading of multiple cards, 2536 To enable the auto-loading of multiple cards, specify the number of
2613 sound cards in that option. 2537 sound cards in that option.
2614 2538
2615 When multiple cards are available, it'd bette 2539 When multiple cards are available, it'd better to specify the index
2616 number for each card via module option, too, 2540 number for each card via module option, too, so that the order of

2635 (index 0) and ens1371 as the second (index 1) 2559 (index 0) and ens1371 as the second (index 1).
2636 2560
2637 Alternative (and new) way to fixate the slot 2561 Alternative (and new) way to fixate the slot assignment is to use
2638 ``slots`` option of snd module. In the case 2562 ``slots`` option of snd module. In the case above, specify like the
2639 following: 2563 following:

2642 options snd slots=snd-interwave,snd-ens13 2566 options snd slots=snd-interwave,snd-ens1371

2644 Then, the first slot (#0) is reserved for snd 2568 Then, the first slot (#0) is reserved for snd-interwave driver, and
2645 the second (#1) for snd-ens1371. You can omi 2569 the second (#1) for snd-ens1371. You can omit index option in each
2646 driver if slots option is used (although you 2570 driver if slots option is used (although you can still have them at
2647 the same time as long as they don't conflict) 2571 the same time as long as they don't conflict).
2648 2572
2649 The slots option is especially useful for avo 2573 The slots option is especially useful for avoiding the possible
2650 hot-plugging and the resultant slot conflict. 2574 hot-plugging and the resultant slot conflict. For example, in the
2651 case above again, the first two slots are alr 2575 case above again, the first two slots are already reserved. If any
2652 other driver (e.g. snd-usb-audio) is loaded b 2576 other driver (e.g. snd-usb-audio) is loaded before snd-interwave or
2653 snd-ens1371, it will be assigned to the third 2577 snd-ens1371, it will be assigned to the third or later slot.
2654 2578

2656 modules but that name. For example, ``slots= 2580 modules but that name. For example, ``slots=!snd-pcsp`` will reserve
2657 the first slot for any modules but snd-pcsp. 2581 the first slot for any modules but snd-pcsp.
