Fix up SCI0_LATE variant of the driver so that it actually plays anything (and even correctly). SCI1 hasn't seen any testing from me so far. I don't know whether that version works. Same for SCI0_EARLY...
I haven't found an elegant and non-intrusive way to squeeze SCI0 support into LordHoto's existing code. The drivers are too different. So I made some rearrangements. The basic mechanisms of LordHoto's SCI1 code should remain the same as before, though. I only introduced some more classes, moved some code into these classes and renamed some things (mainly for myself, so as not to get confused).
I fixed two voice mapping bugs in the existing driver code. The first bug in bindVocies() effectively hindered the driver from playing anything at all when the CMS_DISABLE_VOICE_MAPPING #define wasn't set (_voice[i].channel == 0xFF instead of _voice[i].channel != 0xFF). The second bug in unbindVoices() was not a complete show stopper, but the function simply did not "unbind the voice". The line which does the actual removal of the channel assignment was missing.
The SCI0 driver portions have been tested with: PQ2, KQ4, LSL3, QFG1, ICE and COC.
SCI_0_EARLY versions apparently don't support the CMS. At least I haven't seen a driver file so far. And there seems to be no no instrument patch resource. Although the latter issue needn't necessarily be one, since the patch data array in the driver is actually preset with data (which gets overwritten as soon as a patch file is loaded). Maybe this would work for SCI_0_EARLY. However, I haven't tested this, since I really would have have a look at a driver file first if one actually exists. For now, I have limited the driver to SCI_0_LATE.
SCI1 has been tested with KQ5 and LSL5 (not extensively, just to see whether anything got broken and whether my voice mapping fixes work).

This adds specific support for SCI0_EARLY targets.
Based on and tested with Christmas Cards 1988.
I've not added the volume reset (neither for SCI0_EARLY nor SCI0_LATE), since the ScummVM driver seems to handle volume differently on purpose (probably based on SCI1?).
The square sound channels will be out of spec when playing on the lowest octave. The result is a rather ugly noise. This bug makes a rather subtle appearance if the channel remapping is accurate, but it becomes quite obvious in the SQ4 intro with the current implementation. This commit turns off the channel when trying to play out of spec.
I put this in an separate commit to make it easier to review/revert. I've tried to make this as minimum invasive as possible. That's why I put this in place of the former call to onNewSound().
SCI_0_LATE sound drivers (probably also SCI_0_EARLY, but I don't know that) do some midi track initialization, mostly resetting certain values and assigning voices (hardware channels) to midi parts. The information for this comes from the track header.
The SCI0 version of the PC-98 sound driver relies on this code. The driver checks the channel flags with two different masks and assigns different sound channel types accordingly. This can't be done with the 0x4B event. Using the 0x4B event is sort of counter intuitive anyway, since only some of the SCI0 drivers even support that event.
It seems that the only driver making use of onNewSound() was MT-32. I've adapted the driver to my changes, although I am quite sure that the sound will be unaffected. The only thing that the MT-32 driver does with the header information is checking whether a midi part should play or not and assign exactly one timbre (with exactly the same number) to that part if required.
This fixes two evalutation issues specific to the MSVC x64 release build (other builds worked fine).
This also fixes an analysis warning regarding my use of the span code.
Tell MidiDriver_AmigaMac the game's platform instead of it
attempting to infer this by which patch resources exist.
Fixes bug #10925 where SQ3 German Amiga is treated as Mac because
it happens to contain a patch 7 resource.
By default, frac_t is interpreted as signed. The resulting range isn't
large enough to store offsets, so we interpret it as unsigned here
instead. Fixes a crash in QfG1/Mac where instrument->loop_size is 49457.
Due to the need to calculate the audio duration with millisecond
precision from the file size, it is possible to overflow a 32-bit
integer in games with long background audio loops, like RAMA,
during the calculation of the duration.
It is also not necessary to give some framerate here, so eliminate
the unnecessary explicit Timestamp construction with the second
argument.
Set the default reverb configuration present in either the MT-32
patch data or MT32.DRV of SCI0 games before playing each sound, as
a previously played sound may have changed it.
Also, do not perform a general reverb init, since the start of a
sound will do that now.
Closes gh-1023.
If the user has "Prefer digital sound effects" disabled for a SCI0
game, do not play the digital sample version of a sound resource, if
such data is present. When the resource has only digital sample data
and no MIDI information, play the sample instead.
Closes gh-1022.
Trying to find differences in Lighthouse's audio sample playback,
I discovered that SCI3 had its own variant of handling volumes and
sending this volume information back to game scripts. It is not
known if this fixes any sound bug.
Which were originally only played, when using the Windows interpreter.
Afaik the DOS interpreter was incapable of playing more than 1
sample at a time, which was probably the reason why Sierra only
added these for the Windows interpreter.
For example a sample is now played, when points are awarded.
Those samples are currently used all the time and will also
enhance the game, when platform DOS is chosen.
In case someone wishes to opt-out of this, we could add a game
specific option.
We do something like this for Space Quest 3 already,
that's why I don't see a reason to add a game option right now.
Real MIDI devices, and MT-32 in particular, need delays between
SysEx messages to ensure sufficient time to receive and process
the incoming data buffer. Sending too much data too quickly to
these devices can cause them to crash with a buffer overflow.
The MT-32 emulator, on the other hand, has no problem receiving
SysEx data instantly, so skipping the delays means that games that
send lots of data to the MT-32 will start up much faster.
This update should give the game the default mix it receives in
Windows. If necessary, the half-volume audio bug in the DOS
interpreter can be added as an additional hack for this game, since
there are still some sub-par audio mixes that might need additional
correction (like Curtis talking to Blob when taking her out of the
cage in his apartment at the start of the game) which were also
bad in the Windows version of the game.
Fixes Trac#10165.
This was happening in games with game scripts that control the
master volume themselves by applying the master volume to each
channel sent to the kernel, instead of relying on the kernel to
manage the master volume for them.
This can occur when a save game from the past is loaded and the
audio system was paused prior to loading the save game. This was
fixed eventually in SSCI somewhere around GK2, since it pauses
all audio before restoring a game and then resumes it after the
save game is loaded (after all of the audio channels have been
added from the save game). Since this would seem to be a problem
for earlier games as well, this change is applied universally
instead of being conditionally applied only to the games with
interpreters containing this change.
This patch contains some additional sanity checks that emit
warnings if individual channels end up being started from the
future. There was never such checking in SSCI, and it does not
seem likely to ever happen, but it is unclear right now if this is
an actual problem or not.
Since Resource::makeStream returns a MemoryReadStream which will
not attempt to free the resource memory, it is fine to always
dispose those streams and get rid of the separate resourceStream
property, which was a holdover from some past WIP resource design
which no longer exists.
makeSOLStream was leaking the SeekableSubReadStream object it
creates itself if it was not called with DisposeAfterUse::YES. That
substream is an implementation detail which should not rely on
the caller to be destroyed.
This fixes at least the character selection screen in QFG4CD,
where the sound for the torches is supposed to loop, but wasn't
because kDoSoundSetLoop would bail out before setting the loop
property on the soundObj.
Upon investigation of Sound code across SCI32 games, it was
determined that there are actually (at least) 3 different
revisions, not just a single SCI2.1 version. This patch only
changes the parts of Sound code that are relevant to the correct
use of Audio32.
Fixes Trac#9736, Trac#9756, Trac#9767, Trac#9791.
