Ive never heard of such a config for hdmi. My myth box does hdmi out i plug a hdmi cable from the computer to the tv. audio and video both go over the same cable. Selecting the right profile in pulse audio activated things correctly. i get sound though my tv. due to the way hdmi works you do not get volume control on your computer. it passes a constant signal which the end device uses to control volume. likely the device is muted by default. > > So, one needs to ensure the output is configured correctly. > > The only relevant configuration I see for sound is under the hardware > tab. Anything analog gives an output on the computer, anything digital > gives no output. In both cases, there is no output on the TV. Dennis
