In the case 2635 ``slots`` option of snd module. In the case above, specify like the 2639 following: 2636 following: 2640 :: 2637 :: 2641 2638 2642 options snd slots=snd-interwave,snd-ens13 2639 options snd slots=snd-interwave,snd-ens1371 2643 2640 2644 Then, the first slot (#0) is reserved for snd 2641 Then, the first slot (#0) is reserved for snd-interwave driver, and 2645 the second (#1) for snd-ens1371. You can omi 2642 the second (#1) for snd-ens1371. You can omit index option in each 2646 driver if slots option is used (although you 2643 driver if slots option is used (although you can still have them at 2647 the same time as long as they don't conflict) 2644 the same time as long as they don't conflict). 2648 2645 2649 The slots option is especially useful for avo 2646 The slots option is especially useful for avoiding the possible 2650 hot-plugging and the resultant slot conflict. 2647 hot-plugging and the resultant slot conflict. For example, in the 2651 case above again, the first two slots are alr 2648 case above again, the first two slots are already reserved. If any 2652 other driver (e.g. snd-usb-audio) is loaded b 2649 other driver (e.g. snd-usb-audio) is loaded before snd-interwave or 2653 snd-ens1371, it will be assigned to the third 2650 snd-ens1371, it will be assigned to the third or later slot. 2654 2651 2655 When a module name is given with '!', the slo 2652 When a module name is given with '!', the slot will be given for any 2656 modules but that name. For example, ``slots= 2653 modules but that name. For example, ``slots=!snd-pcsp`` will reserve 2657 the first slot for any modules but snd-pcsp. 2654 the first slot for any modules but snd-pcsp. 2658 2655 2659 2656 2660 ALSA PCM devices to OSS devices mapping 2657 ALSA PCM devices to OSS devices mapping 2661 ======================================= 2658 ======================================= 2662 :: 2659 :: 2663 2660 2664 /dev/snd/pcmC0D0[c|p] -> /dev/audio0 (/d 2661 /dev/snd/pcmC0D0[c|p] -> /dev/audio0 (/dev/audio) -> minor 4 2665 /dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev 2662 /dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev/dsp) -> minor 3 2666 /dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/de 2663 /dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/dev/adsp) -> minor 12 2667 /dev/snd/pcmC1D0[c|p] -> /dev/audio1 2664 /dev/snd/pcmC1D0[c|p] -> /dev/audio1 -> minor 4+16 = 20 2668 /dev/snd/pcmC1D0[c|p] -> /dev/dsp1 2665 /dev/snd/pcmC1D0[c|p] -> /dev/dsp1 -> minor 3+16 = 19 2669 /dev/snd/pcmC1D1[c|p] -> /dev/adsp1 2666 /dev/snd/pcmC1D1[c|p] -> /dev/adsp1 -> minor 12+16 = 28 2670 /dev/snd/pcmC2D0[c|p] -> /dev/audio2 2667 /dev/snd/pcmC2D0[c|p] -> /dev/audio2 -> minor 4+32 = 36 2671 /dev/snd/pcmC2D0[c|p] -> /dev/dsp2 2668 /dev/snd/pcmC2D0[c|p] -> /dev/dsp2 -> minor 3+32 = 39 2672 /dev/snd/pcmC2D1[c|p] -> /dev/adsp2 2669 /dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44 2673 2670 2674 The first number from ``/dev/snd/pcmC{X}D{Y}[ 2671 The first number from ``/dev/snd/pcmC{X}D{Y}[c|p]`` expression means 2675 sound card number and second means device num 2672 sound card number and second means device number.
