123 Module snd-adlib
124 ----------------
125
126 Module for AdLib FM cards.
127
128 port - port # for OPL chip

130 This module supports multiple cards. It does not support autoprobe, so
131 the port must be specified. For actual AdLib FM cards it will be 0x388.
132 Note that this card does not have PCM support and no mixer; only FM
133 synthesis.
134
135 Make sure you have "sbiload" from the alsa-tools package available and,
136 after loading the module, find out the assigned ALSA sequencer port
137 number through "sbiload -l". Example output:
138
139 Port Client name Port name
140 64:0 OPL2 FM synth OPL2 FM Port
141
142 Load the std.sb and drums.sb patches also supplied by sbiload:
143
144 sbiload -p 64:0 std.sb drums.sb
145
146 If you use this driver to drive an OPL3, you can use std.o3 and drums.o3
147 instead. To have the card produce sound, use aplaymidi from alsa-utils:
148
149 aplaymidi -p 64:0 foo.mid
