Pulseaudio Stream Volume Issue

I have an issue with Pulseaudio when I change youtube playback volume in IceCat it changes stream volume in pulsemixer. I tested it with IceCat, Firefox, surf (which is basically webkitprocess).

Here are results.

******

1. Firefox: changing youtube volume DOES NOT (Update: it DOES ) change stream volume in pulsemixer
2. IceCat: changing youtube volume CHANGES stream volume in pulsemixer
3. surf(webkitprocess): changing youtube volume CHANGES stream volume in pulsemixer

Additional Information

******

1. I use void with xorg/dwm
2. my user does have audio group
3. I run pulseaudio as user (not as system daemon)
4. flat-volumes = no
5. I have alsa-plugins-pulseaudio and alsa-lib but no regular alsa
6. my asound.conf file:Code:pcm.!default {
   type pulse
   hint {
   show on
   description "Default ALSA Output (currently PulseAudio Sound Server)"
   }
   }
   
   ctl.!default {
   type pulse
   }

REALLY hope to find some help!
