Volume slider not working on external speaker (connect thru HDMI ARC)
I have a home theater (external speaker connect thru HDMI ARC) connected to my webostv, the volume slider doesn't work when the external speaker is selected, otherwise the volume buttons work normal with external speaker. Is there a fix for this?
