The speakers and internal microphone on my laptop stopped working.
When I run pavucontrol-qt (Volume Control), Speakers are unavailable as a port on the Output Devices tab. Similarly, the Internal Microphone is "unplugged" as a port on the Input Devices tab under Built-in Audio Analog Stereo. Instead the Output Devices port is "Headphones (plugged in)" and the Input Devices port is "Microphone (plugged in)". There is nothing plugged into the 3.5 mm Headphones/Microphone jack.
It seems like the ports need to be reset in some configuration file for PulseAudio or something. I looked at the config files, but I am not sure what to look for or what to change.
Any ideas?
Here's the information about my setup:
My laptop is a Lenovo ThinkPad E590.
