My issue is about sound (main) background, volume has gone up and down when node change, but it happened only on Firefox (v36.0.1, 64bits on wins10) and it seems to work fine on Chrome and MS Edge. How do I fine tune for this issue?

ฺBy the way, this issue just occured after I added sound control from silhouette_volumn_control.ggskc into current skin

Hi Kavin,
Not hearing any background sound, Im only hearing sound from the TV video.
Which seems to play ok.
Can you give me more information on what I should be hearing or not as the case may be.
Regards,
Hopki
