Today, only left speaker works when HDMI is disconnected. If I start on Windows 10, the two speakers are working well.

With UBUNTU 18.04, I had to change manually sound output in parameters, sound board. I have just upgraded to UBUNTU 20.04. Change output seems now automatic. When I connect TV with HDMI, I have sound on TV, but no more possibility to have sound with loudspeakers connected to PC. I must disconnect HDMI cable to find again sound on PC. And change manually sound output in parameters, sound board doesn't work. Thanking you in advance for your help.
