Added and replaced ALSA output with OSS
load-module module-oss device=/dev/dsp sink_name=alsa_output.pci-0000_04_01.0.analog-stereo mmap=1
Note:
- Sound works normally in VMware even if snd_pcm_oss, snd_mixer_oss, snd_seq_oss modules are loaded. And no problems with FlashPlayer. The wmmixer works also good with OSS (alsa-oss) and ALSA, mixers are working on same channes, can mute and unmute each other.
- It is better to install alsa-oss and load oss modules for output instead of alsa modules for output because with alsa modules loaded for output the
exit-idle-time = -1
in the daemon.conf ignored and the daemon going idle and has very hard to came back, only the pavucontrol can bring it back fast and keep until closed or an application playing sound or a volume meter is running. - The load-module module-suspend-on-idle line in the default.pa file makes that pulseaudio never unloads modules or going idle if uncommented.

Fix OSS module load on boot
Fix in case if those configurations will not load modules:
/etc/modprobe.d/snd_pcm_oss.conf
snd_pcm_oss
and
/etc/modprobe.d/snd_pcm_oss.conf
install snd_pcm_oss modprobe -i snd_pcm_oss
