Re: comment 10, I planned four tests (two profiles, normal mode and safe mode). 

First test (default profile, normal mode), in a nutshell: 

service virtual_oss onestart

virtual_oss_ctl -f /dev/vdsp.ctl

YouTube video in Firefox. 

At a glance: 

- the Virtual OSS Control window appeared OK. 


- nothing audible (internal loudspeakers, headset on USB)

- after closing virtual_oss_ctl and stopping the virtual_oss service, 
  playback in Firefox was impossible

- a restart of Firefox did not resolve the situation

- reboot -r 
  without attempting to start the virtual_oss service 
  did not resolve the situation (still, no playback in Firefox)

- a full restart of the system 
  without attempting to start the virtual_oss service 
  was enough to restore playback in Firefox.
