On Windows 98 SE:

 * SB16: System hangs as described in this bug report
 * ES1370: Causes system freeze with back screen at boot time
 * AC97 (as suggested here: 
https://smcv.pseudorandom.co.uk/2015/discworldnoir/): BSODs during the 
 * GUS: Device is not even detected

Conclusion: At the moment, there is no way to get audio output from
Windows 98 se VM.

  Temporal freeze and slowdown while using emulated sb16

Status in QEMU:

Bug description:
  I have been carrying around this bug since previous versions and on
  different machines: When I use the -soundhw sb16 option, while playing
  any sound on the virtual machine it temporally freezes the emulated
  machine and loops the last bit of such sound effect for 1-2 minutes,
  then goes back to normal speed (until a new sound is played).

  Console shows:

   sb16: warning: command 0xf9,1 is not truly understood yet
   sb16: warning: command 0xf9,1 is not truly understood yet
  main-loop: WARNING: I/O thread spun for 1000 iterations

  -One of my emulated machines is Windows 3.11: I managed to overrun
  this bug by switching from the local 1.5 version of the sound blaster
  driver to the 1.0, although since I updated qemu it freezes that
  machine, so I can't test if it still works.

  I am using the 1.7.90 version, but I suffered this bug for over one
  year (confirmed in version 2.0.0-rc0 too)

  this bug happens anytime I use the -soundhw sb16 switch, but the full
  command I am using in this specific case is:

  qemu-system-i386 -localtime -cpu pentium -m 32 -display sdl -vga
  cirrus -hda c.img -cdrom win95stuff.iso -net nic,model=ne2k_pci -net
  user -soundhw sb16

  This bug appears on all my machines: Pentium III running Slackware
  13.0 and freeBSD 10; Dual core T2400, both in Arch, Gentoo and
  Slackware 14.1 (all 32 bits), and a Dual core T4400 64 bits with
  Gentoo and Slackware. Same problem in all of those systems after
  compiling instead of using the distro packages....
