I tried to use the WSS emulation instead, with the sb8 module, and the
fm is working fine in this mode (playmidi) :-) But the pcm sound is
crappy :-(
I noticed that changing OPL3_HW_OPL3_CS to OPL3_HW_AUTO when calling
snd_opl3_create() in cards/card-cs4236.c forces the opl3 autodetection,
and the autodetection in snd_opl3_detect() fails for my chipset :
Dec 19 00:27:29 localhost kernel: ALSA opl3.c:128: OPL3: stat1 = 0xff
Dec 19 00:27:29 localhost kernel: ALSA card-cs4236.c:486: CS4236+: OPL3 not detected

Is the opl3 autodetection supposed to fail for this chipset ?
Is it possible to use the FM through the WSS emulation while
using the regular cs4236 driver ?
