i have these Games, the boxes of them all - they are the best.
I have them all running through Dosbox and they have sound, and music too if i recall.
the dosbox settings for the sound setup i have are the following - see if these are any different to what you have
nosound=false
swapstereo=false
rate=44100
blocksize=2048
prebuffer=50
[midi]
# mpu401: Type of MPU-401 to emulate.
# Possible values: intelligent, uart, none.
# mididevice: Device that will receive the MIDI data from MPU-401.
# Possible values: default, win32, alsa, oss, coreaudio, coremidi, mt32, synth, timidity, none.
# midiconfig: Special configuration options for the device driver. This is usually the id of the device you want to use.
# or in the case of coreaudio, you can specify a soundfont here.
# When using a Roland MT-32 rev. 0 as midi output device, some games may require a delay in order to prevent 'buffer overflow' issues.
# In that case, add 'delaysysex', for example: midiconfig=2 delaysysex
# See the README/Manual for more details.
# mt32.reverse.stereo: Reverse stereo channels for MT-32 output
# Possible values: off, on.
# mt32.verbose: MT-32 debug logging
# Possible values: off, on.
# mt32.thread: MT-32 rendering in separate thread
# Possible values: off, on.
# mt32.dac: MT-32 DAC input emulation mode
# Nice = 0 - default
# Produces samples at double the volume, without tricks.
# Higher quality than the real devices
#
# Pure = 1
# Produces samples that exactly match the bits output from the emulated LA32.
# Nicer overdrive characteristics than the DAC hacks (it simply clips samples within range)
# Much less likely to overdrive than any other mode.
# Half the volume of any of the other modes, meaning its volume relative to the reverb
# output when mixed together directly will sound wrong. So, reverb level must be lowered.
# Perfect for developers while debugging
#
# GENERATION1 = 2
# Re-orders the LA32 output bits as in early generation MT-32s (according to Wikipedia).
# Bit order at DAC (where each number represents the original LA32 output bit number, and XX means the bit is always low):
# 15 13 12 11 10 09 08 07 06 05 04 03 02 01 00 XX
#
# GENERATION2 = 3
# Re-orders the LA32 output bits as in later geneerations (personally confirmed on my CM-32L - KG).
# Bit order at DAC (where each number represents the original LA32 output bit number):
# 15 13 12 11 10 09 08 07 06 05 04 03 02 01 00 14
#
# Possible values: 0, 1, 2, 3, auto.
# mt32.reverb.mode: MT-32 reverb mode
# Possible values: 0, 1, 2, 3, auto.
# mt32.reverb.time: MT-32 reverb decaying time
# Possible values: 0, 1, 2, 3, 4, 5, 6, 7.
# mt32.reverb.level: MT-32 reverb level
# Possible values: 0, 1, 2, 3, 4, 5, 6, 7.
# mt32.partials: MT-32 max partials allowed (0-256)

[sblaster]
# sbtype: Type of Soundblaster to emulate. gb is Gameblaster.
# Possible values: sb1, sb2, sbpro1, sbpro2, sb16, sb16vibra, gb, none.
# sbbase: The IO address of the soundblaster.
# Possible values: 220, 240, 260, 280, 2a0, 2c0, 2e0, 300.
# irq: The IRQ number of the soundblaster.
# Possible values: 7, 5, 3, 9, 10, 11, 12.
# dma: The DMA number of the soundblaster.
# Possible values: 1, 5, 0, 3, 6, 7.
# hdma: The High DMA number of the soundblaster.
# Possible values: 1, 5, 0, 3, 6, 7.
# sbmixer: Allow the soundblaster mixer to modify the DOSBox mixer.
# oplmode: Type of OPL emulation. On 'auto' the mode is determined by sblaster type.
# All OPL modes are Adlib-compatible, except for 'cms'. sbtype=none
# together with oplmode=cms will emulate a Gameblaster.
# Possible values: auto, cms, opl2, dualopl2, opl3, none, hardware, hardwaregb.
# oplemu: Provider for the OPL emulation. compat might provide better quality (see oplrate as well).
# Possible values: default, compat, fast.
# oplrate: Sample rate of OPL music emulation. Use 49716 for highest quality (set the mixer rate accordingly).
# Possible values: 44100, 49716, 48000, 32000, 22050, 16000, 11025, 8000.
# hardwarebase: base address of the real hardware soundblaster:
# 210,220,230,240,250,260,280
# goldplay: Enable goldplay emulation.
