Just got my Pi-top4 today. All was going well until l I ran the updater. After the system files updated I have lost sound on the internal speaker. If I go to the sound icon in the bottom right of the screen the options are now HDMI and AV Jack, before it was Analog and HDMI. Not sure if that is the cause of the problem. I have re flashed the micro SD card and tested again with the same result, The internal speaker works until l I update the system.
Any ideas guys?
