I have an Acer Aspire 5741 with Intel Graphics HD. On Ubuntu 12.04, I get low volume through HDMI. Moreover, I can't increase using the TV volume control. On the contrary, on Windows / HDMI volume is higher and I am also able to adjust the volume using TV volume control.
I am trying to play videos on my TV using Totem.
What is the reason for this difference? Any solutions?
