Here is what I found out about sound on my tecra 750cdt:
1. Sound is mute after a resume (some apm issue). So you must compile as a
module and reinsert this after a resume (can be done automatically).
2. Don't configure it as sb compatible or you get 8bit.
3. I had no luck with OSS (a year ago though) and don't like that
closed-source binary junk anyway.
4. Sound does not seem to work correctly unless I make the following changes
to the kernel sound sources: (1) Tell it that irq5 is fine for MSS, (2)
comment out all traces of something called DESKPROXL which seems to break
MSS sound. I have enclosed a patch below.
5. I use the following as kernel config:
#
# Sound
#
CONFIG_SOUND=m
# CONFIG_SOUND_ES1370 is not set
# CONFIG_SOUND_ES1371 is not set
# CONFIG_SOUND_SONICVIBES is not set
# CONFIG_SOUND_MSNDCLAS is not set
# CONFIG_SOUND_MSNDPIN is not set
CONFIG_SOUND_OSS=m
# CONFIG_SOUND_PAS is not set
# CONFIG_SOUND_SB is not set
CONFIG_SOUND_ADLIB=m
# CONFIG_SOUND_GUS is not set
CONFIG_SOUND_MPU401=m
# CONFIG_SOUND_PSS is not set
CONFIG_SOUND_MSS=m
# CONFIG_SOUND_SSCAPE is not set
# CONFIG_SOUND_TRIX is not set
# CONFIG_SOUND_MAD16 is not set
# CONFIG_SOUND_WAVEFRONT is not set
# CONFIG_SOUND_CS4232 is not set
# CONFIG_SOUND_OPL3SA2 is not set
# CONFIG_SOUND_MAUI is not set
# CONFIG_SOUND_SGALAXY is not set
# CONFIG_SOUND_AD1816 is not set
# CONFIG_SOUND_OPL3SA1 is not set
# CONFIG_SOUND_SOFTOSS is not set
CONFIG_SOUND_YM3812=m
# CONFIG_SOUND_VMIDI is not set
# CONFIG_SOUND_UART6850 is not set
6. I put the following into /etc/conf.modules (I use debian if it matters)
alias char-major-14 ad1848
alias synth0 adlib_card
options ad1848 io=0x530 irq=5 dma=1 dma2=0
options mpu401 io=0x330 irq=-5
options adlib_card io=0x388
post-install ad1848 gom
irq=-5 means share that irq (?).
gom is a mixer which I use to set sound volume to maximum. Sound is still
not as loud as under windows.
I don't understand exactly what's going on and haven't looked at these
things for months but sound more or less works for me.

PS: I never had any problems getting X to work. Just make sure you
don't use the S3V server. The SVGA server works fine with a plain
standard config.
