2593 The ALSA drivers can be loaded automatically 2567 The ALSA drivers can be loaded automatically on demand by defining
2594 module aliases. The string ``snd-card-%1`` i 2568 module aliases. The string ``snd-card-%1`` is requested for ALSA native
2595 devices where ``%i`` is sound card number fro 2569 devices where ``%i`` is sound card number from zero to seven.
2596 2570
2597 To auto-load an ALSA driver for OSS services, 2571 To auto-load an ALSA driver for OSS services, define the string
2598 ``sound-slot-%i`` where ``%i`` means the slot 2572 ``sound-slot-%i`` where ``%i`` means the slot number for OSS, which
2599 corresponds to the card index of ALSA. Usual 2573 corresponds to the card index of ALSA. Usually, define this
2600 as the same card module. 2574 as the same card module.
2601 2575
2602 An example configuration for a single emu10k1 2576 An example configuration for a single emu10k1 card is like below:

2609 2583
2610 The available number of auto-loaded sound car 2584 The available number of auto-loaded sound cards depends on the module
2611 option ``cards_limit`` of snd module. As def 2585 option ``cards_limit`` of snd module. As default it's set to 1.
2612 To enable the auto-loading of multiple cards, 2586 To enable the auto-loading of multiple cards, specify the number of
2613 sound cards in that option. 2587 sound cards in that option.
2614 2588
2615 When multiple cards are available, it'd bette 2589 When multiple cards are available, it'd better to specify the index
2616 number for each card via module option, too, 2590 number for each card via module option, too, so that the order of
2617 cards is kept consistent. 2591 cards is kept consistent.

2634 In this example, the interwave card is always 2608 In this example, the interwave card is always loaded as the first card
2635 (index 0) and ens1371 as the second (index 1) 2609 (index 0) and ens1371 as the second (index 1).
2636 2610
2637 Alternative (and new) way to fixate the slot 2611 Alternative (and new) way to fixate the slot assignment is to use
2638 ``slots`` option of snd module. In the case 2612 ``slots`` option of snd module. In the case above, specify like the
2639 following: 2613 following:
2640 :: 2614 ::
2641 2615
2642 options snd slots=snd-interwave,snd-ens13 2616 options snd slots=snd-interwave,snd-ens1371
2643 2617
2644 Then, the first slot (#0) is reserved for snd 2618 Then, the first slot (#0) is reserved for snd-interwave driver, and
2645 the second (#1) for snd-ens1371. You can omi 2619 the second (#1) for snd-ens1371. You can omit index option in each
2646 driver if slots option is used (although you 2620 driver if slots option is used (although you can still have them at
2647 the same time as long as they don't conflict) 2621 the same time as long as they don't conflict).
2648 2622
2649 The slots option is especially useful for avo 2623 The slots option is especially useful for avoiding the possible
2650 hot-plugging and the resultant slot conflict. 2624 hot-plugging and the resultant slot conflict. For example, in the
2651 case above again, the first two slots are alr 2625 case above again, the first two slots are already reserved. If any
2652 other driver (e.g. snd-usb-audio) is loaded b 2626 other driver (e.g. snd-usb-audio) is loaded before snd-interwave or
2653 snd-ens1371, it will be assigned to the third 2627 snd-ens1371, it will be assigned to the third or later slot.
2654 2628
2655 When a module name is given with '!', the slo 2629 When a module name is given with '!', the slot will be given for any
2656 modules but that name. For example, ``slots= 2630 modules but that name. For example, ``slots=!snd-pcsp`` will reserve
2657 the first slot for any modules but snd-pcsp. 2631 the first slot for any modules but snd-pcsp.
