[AD] Found the problem with the setup sound core's

[Grzegorz Adam Hankiewicz <gradha@xxxxxxxxxx>]

Hi.

After linking the setup program with static debug libs I got everything I
needed. The problem looks quite simple: I don't have my sound card
configured for midi, so autodetection constantly tells about not being
able to detect synth support. Ok, so in order to enter the test option I
select OSS driver as digital, and none as midi driver. Then, playing wav's
in the background and pressing the test button gives: 

backtrace
#0  0x806d201 in all_notes_off (channel=0) at ./src/midi.c:557
#1  0x806e242 in play_midi (midi=0x0, loop=0) at ./src/midi.c:1197
#2  0x806e33c in stop_midi () at ./src/midi.c:1252
#3  0x806df08 in midi_exit () at ./src/midi.c:1028
#4  0x8070956 in install_sound (digi=-1, midi=-1, cfg_path=0x0) at ./src/sound.c:364
#5  0x804bd56 in init_sound (msg=0x80a4f37 "Sound initialization failed!") at ./setup/setup.c:903
#6  0x804ec25 in main_handler (c=1) at ./setup/setup.c:2320
#7  0x804b5a9 in update () at ./setup/setup.c:734
#8  0x804f901 in _mangled_main () at ./setup/setup.c:2626
#9  0x8078f6e in main (argc=1, argv=0xbffffd74) at ./src/unix/umain.c:39

Looks like at src/sound.c is the digital driver detection. It fails since
I am playing wavs. Now, it calls midi_exit, and there's the problem, it is
not defined. The function calls reach all_notes_off, where it tries to
access midi_driver->raw_midi. print midi_driver shows 0x0, and obviously
trying to do midi_driver->raw_midi dumps core.

If I repeat the same without wav files I can enter without problems the
test dialog and ring the bells. There lies the problem: calling midi_exit
with midi_driver being NULL. I don't know however where/what should I
change. I would change midi_exit to:

static void midi_exit(void)
{
   if (midi_exit) stop_midi();
}

But I don't really know if that doesn't leave more midi_driver == NULL
leaks somewhere else.

After modprobing adlib_card OSS works with midi, but I still can't hear
any midi. I guess this is because I didn't configure my card yet. In fact,
I have AWE and OPL support disabled in the kernel...
