2593 The ALSA drivers can be loaded automatically 2574 The ALSA drivers can be loaded automatically on demand by defining
2594 module aliases. The string ``snd-card-%1`` i 2575 module aliases. The string ``snd-card-%1`` is requested for ALSA native
2595 devices where ``%i`` is sound card number fro 2576 devices where ``%i`` is sound card number from zero to seven.
2596 2577
2597 To auto-load an ALSA driver for OSS services, 2578 To auto-load an ALSA driver for OSS services, define the string
2598 ``sound-slot-%i`` where ``%i`` means the slot 2579 ``sound-slot-%i`` where ``%i`` means the slot number for OSS, which
2599 corresponds to the card index of ALSA. Usual 2580 corresponds to the card index of ALSA. Usually, define this
2600 as the same card module. 2581 as the same card module.
2601 2582
2602 An example configuration for a single emu10k1 2583 An example configuration for a single emu10k1 card is like below:

2609 2590
2610 The available number of auto-loaded sound car 2591 The available number of auto-loaded sound cards depends on the module
2611 option ``cards_limit`` of snd module. As def 2592 option ``cards_limit`` of snd module. As default it's set to 1.
2612 To enable the auto-loading of multiple cards, 2593 To enable the auto-loading of multiple cards, specify the number of
2613 sound cards in that option. 2594 sound cards in that option.
2614 2595
2615 When multiple cards are available, it'd bette 2596 When multiple cards are available, it'd better to specify the index
2616 number for each card via module option, too, 2597 number for each card via module option, too, so that the order of
2617 cards is kept consistent. 2598 cards is kept consistent.

2633 2614
2634 In this example, the interwave card is always 2615 In this example, the interwave card is always loaded as the first card
2635 (index 0) and ens1371 as the second (index 1) 2616 (index 0) and ens1371 as the second (index 1).
2636 2617
2637 Alternative (and new) way to fixate the slot 2618 Alternative (and new) way to fixate the slot assignment is to use
2638 ``slots`` option of snd module. In the case 2619 ``slots`` option of snd module. In the case above, specify like the
2639 following: 2620 following:
2640 :: 2621 ::
2641 2622
2642 options snd slots=snd-interwave,snd-ens13 2623 options snd slots=snd-interwave,snd-ens1371
2643 2624
2644 Then, the first slot (#0) is reserved for snd 2625 Then, the first slot (#0) is reserved for snd-interwave driver, and
2645 the second (#1) for snd-ens1371. You can omi 2626 the second (#1) for snd-ens1371. You can omit index option in each
2646 driver if slots option is used (although you 2627 driver if slots option is used (although you can still have them at
2647 the same time as long as they don't conflict) 2628 the same time as long as they don't conflict).
2648 2629
2649 The slots option is especially useful for avo 2630 The slots option is especially useful for avoiding the possible
2650 hot-plugging and the resultant slot conflict. 2631 hot-plugging and the resultant slot conflict. For example, in the
2651 case above again, the first two slots are alr 2632 case above again, the first two slots are already reserved. If any
2652 other driver (e.g. snd-usb-audio) is loaded b 2633 other driver (e.g. snd-usb-audio) is loaded before snd-interwave or
2653 snd-ens1371, it will be assigned to the third 2634 snd-ens1371, it will be assigned to the third or later slot.
2654 2635
2655 When a module name is given with '!', the slo 2636 When a module name is given with '!', the slot will be given for any
2656 modules but that name. For example, ``slots= 2637 modules but that name. For example, ``slots=!snd-pcsp`` will reserve
2657 the first slot for any modules but snd-pcsp. 2638 the first slot for any modules but snd-pcsp.
