Be sure to check the game or application’s graphics settings for any options related to multiple displays. Note that if you plan to manage full-screen apps like games across multiple monitors, the game or app itself may have its own multi-display settings within the program. Select “Extend” by clicking or using the arrow keys and the Enter key. To enable Extend mode, press Windows+P to open up the “Project” menu. Extend mode spreads your desktop between all of your available displays, so it’s like having one gigantic virtual workspace. Type “sound” in Unity dash (by pressing the Super/Windows key) or from the top right corner choose the system settings and then look for sound setting.To move windows between multiple monitors, Extend mode must be enabled. The reason in my case was that the default sound setting was “built-in speaker audio”. Thankfully this problem was not complex, at least in this case with Ubuntu 12.04. I saw a number of forum posts with trouble on the audio problem in extended monitor in Ubuntu.
Fix no audio through HDMI in Ubuntu Solution 1: Change default sound setting Though I did it for Ubuntu, I presume these solutions should also work for Linux Mint, elementary OS and other Linux distributions based on Ubuntu. But the previous time I could see HDMI option in the input audio source but in Ubuntu 15.04, HDMI audio option was not even listed in the input audio source so a switch to HDMI input was (seemingly) impossible.įor this reason, I decided to upgrade this article with new solutions so that you could fix no sound through HDMI problem in Ubuntu 12.04, 14.04 and 15.04. This post was written more than two years ago when I faced similar situation with Ubuntu 12.04. I have been in this situations in the past when HDMI audio not working in Ubuntu.
The movie was displayed in the TV but the audio was still coming through laptop’s inbuilt speakers. To my surprise, there was no sound through HDMI in TV.
The other day, I connected my Acer Aspire R13 running Ubuntu 15.04 with my Samsung TV to watch a movie.
