Found the problem: FSReadFork returns eofErr when the file is finished.
However, we check its return value for errors, and if anything but
noErr occurs, the reader thread aborts its current iteration. That is
bad, because it aborts before it can ever set the flag which tells that
the file is over (also, any remaining data which FSRead did return is
lost - so you'd not hear about to 4 seconds from the end of the file.
Furthermore, the computed data size was 8 bytes to high (I forgot to
account for the fact that the size of an (A)IFF chunk always contains
the chunk header & size fields, too). This is enough to make it work.
However, the end condition is rather fragile, so I tuned some other
things to be pessimistic (check for <= 0 instead of == 0, when eofErr
is encountered enforce mReadFilePosition == mFileLength). You never
know...
The attached patch fixes the issue for me.

2 All: | |
3 Audio rate conversion is only implemented by multiplying or dividing | |
4 by a power of two. This is a side-effect of the requirement that the | |
5 raw audio buffer size be a power of two, and can hopefully be fixed. | |
6 This means 8 KHz audio converted to 22 KHz ends up being 16 KHz. :-/ | |
7 | |
8 When the implementation is writing directly to video memory the mouse | |
9 cursor doesn't work properly. Applications which do this should use | |
10 their own mouse cursor and call SDL_ShowCursor(0) to hide the system | |
11 cursor. | |
12 | |
13 Linux: | |
14 Wide UNICODE character input (Kanji, etc.) is not yet supported. | |
15 It requires handling of keyboard mapping events and using the XIM | |
16 input translation extension. I will implement it as requested. | |
17 Latin-1 keyboard input works fine. | |

0 | 21 The AAlib, GGI, and SVGAlib video drivers are not heavily tested. |
22 | |
23 Win32: | |
24 The MCI driver can't tell if the CD-ROM drive is paused or stopped. | |
25 | |
26 The SDL_INIT_EVENTTHREAD flag is not supported on Win32 | |
27 (Idea: create a separate DirectInput polling thread) | |
28 The main purpose of this flag is for smooth cursor motion in | |
29 fullscreen environments. | |
30 | |
31 Wide UNICODE character input (Kanji, etc.) is not yet supported. | |
32 This requires the ToUnicode() API which is only implemented on | |
33 Windows NT/2000, not on Windows 95/98. | |
34 Latin-1 keyboard input works fine. | |
35 | |
36 Joysticks are only supported under the Win32 MultiMedia API, | |
37 DirectInput support is not yet implemented. | |
38 | |
39 BeOS: | |
40 BePPC is not supported, apparently not even by Be Inc. | |
41 | |
42 SDL_WM_GrabInput() is not implemented. | |
43 Does anyone know how to do this? SDL_WM_GrabInput() is designed | |
44 to prevent the user from switching input and mouse focus away from | |
45 the SDL application. | |
46 | |
47 Continuous relative mouse motion is not implemented. | |
48 | |
49 Wide UNICODE character input (Kanji, etc.) has not been tested. | |
50 Latin-1 keyboard input works fine. | |
51 | |
52 MacOS: | |
53 Palette handling isn't implemented in windowed mode yet. | |
54 | |
55 Audio hasn't been extensively tested, in particular the locking | |
56 isn't implemented and mixer routines may not call malloc() or free() | |
57 because they are called at interrupt time. | |
58 | |
59 SDL_WM_GrabInput() is not implemented. | |
60 Does anyone know how to do this? SDL_WM_GrabInput() is designed | |
61 to prevent the user from switching input and mouse focus away from | |
62 the SDL application. | |
63 | |
64 Continuous relative mouse motion is not implemented. | |
65 | |
66 SDL_AddTimer() and SDL_RemoveTimer() haven't been implemented yet. | |
67 | |
68 Not all of the keys are properly recognized on the keyboard. | |
