I connected my laptop with TV through HDMI to watch a movie with some friends and all went well. The sound was giong through HDMI, and I had no problems. However, when I turned the computer on today, I noticed there is no sound. I went to sound settings in system settings and found out that ubuntu still sends sound through HDMI. Restarting computer doesn't help. Here's a screenshot:
As you can see, the sound is going through HDMI, and there is no sound from speakers. Restarting the computer doesn't help. Please help! Thank you!
