Hi,

If you:

dd if=/dev/dsp of=/dev/dsp bs=128

Do you hear yourself?

Also, did you restart pulseaudio or any other daemon using /dev/dsp ? 
Possibly you'll need a special config entry for /dev/dsp for pulseaudio, 
if firefox is using that, because Virtual OSS devices are not listed in 
/dev/sndstat which pulseaudio scans.
