2477 specific devices on drivers for on-board AC'97 controllers like
2478 snd-intel8x0. Some hardware have swapped output pins between Master
2480 specifications from version to version :-)
2482 The driver provides the auto-detection of known problematic devices,
2507 For backward compatibility, the corresponding integer value -1, 0, ...
2514 Configuring Non-ISAPNP Cards
2517 When the kernel is configured with ISA-PnP support, the modules
2519 If this option is set, *only* the ISA-PnP devices will be probed.
2520 For probing the non ISA-PnP cards, you have to pass ``isapnp=0`` option
2523 When the kernel is configured without ISA-PnP support, isapnp option
2531 module aliases. The string ``snd-card-%1`` is requested for ALSA native
2532 devices where ``%i`` is sound card number from zero to seven.
2534 To auto-load an ALSA driver for OSS services, define the string
2535 ``sound-slot-%i`` where ``%i`` means the slot number for OSS, which
2536 corresponds to the card index of ALSA. Usually, define this
2537 as the same card module.
2539 An example configuration for a single emu10k1 card is like below:
2542 ----- /etc/modprobe.d/alsa.conf
2543 alias snd-card-0 snd-emu10k1
2544 alias sound-slot-0 snd-emu10k1
2545 ----- /etc/modprobe.d/alsa.conf
2547 The available number of auto-loaded sound cards depends on the module
2549 To enable the auto-loading of multiple cards, specify the number of
2553 number for each card via module option, too, so that the order of
2559 ----- /etc/modprobe.d/alsa.conf
2562 alias snd-card-0 snd-interwave
2563 alias snd-card-1 snd-ens1371
2564 options snd-interwave index=0
2565 options snd-ens1371 index=1
2567 alias sound-slot-0 snd-interwave
2568 alias sound-slot-1 snd-ens1371
2569 ----- /etc/modprobe.d/alsa.conf
2571 In this example, the interwave card is always loaded as the first card
2579 options snd slots=snd-interwave,snd-ens1371
2581 Then, the first slot (#0) is reserved for snd-interwave driver, and
2582 the second (#1) for snd-ens1371. You can omit index option in each
2587 hot-plugging and the resultant slot conflict. For example, in the
2589 other driver (e.g. snd-usb-audio) is loaded before snd-interwave or
2590 snd-ens1371, it will be assigned to the third or later slot.
2593 modules but that name. For example, ``slots=!snd-pcsp`` will reserve
2594 the first slot for any modules but snd-pcsp.
