1 Documentation for the ESS1868F AudioDrive PnP sound card
3 The ESS1868 sound card is a PnP ESS1688-compatible 16-bit sound card.
5 Notes about configuring the sound card:
7 * The ESS1868 does not allow use of a 16-bit DMA, thus DMA 0, 1, 2, and 3
10 * isapnptools version 1.14 does work with ESS1868. Earlier versions might
13 * Sound support MUST be compiled as MODULES, not statically linked
16 For configuring the sound card's I/O addresses, IRQ and DMA, here is a
17 sample copy of the isapnp.conf directives regarding the ESS1868:
19 (CONFIGURE ESS1868/-1 (LD 1
24 (INT 0 (IRQ 5 (MODE +E)))
28 (for a full working isapnp.conf file, remember the

35 In this setup, the main card I/O is 0x0220, FM synthesizer is 0x0388, and
36 the MPU-401 MIDI port is located at 0x0330. IRQ is IRQ 5, DMA is channel 1.
38 After configuring the sound card via isapnp, to use the card you must load
39 the sound modules with the proper I/O information. Here is my setup:
41 # ESS1868F AudioDrive initialization
45 /sbin/insmod sb io=0x220 irq=5 dma=1 dma16=-1
46 /sbin/insmod mpu401 io=0x330
47 /sbin/insmod opl3 io=0x388
50 opl3 is the FM synthesizer--I have not tried the SoftOSS wavetable
51 synthesizer yet, but I assume it would work as well. Also, doing:
53 /sbin/insmod adlib_card io=0x388
54 works, but I believe the sound quality is a bit distorted when playing MIDI
57 When using the above setup, my /proc/sound gives the following:
