I cleaned the keyboard of my X1 carbon today, which inevitably involved pressing all keys on the keyboard randomly. Immediately after the cleaning, the speaker can't produce any sound. Headphones work fine.
I checked the sound option in control panel, and everything seems to be working normally. The green bar that shows the changing volume of speaker perfectly respond to the system and browser, except no sound is actually produced. It also shows that the sound card is working fine.
Does that mean that my speakers are broken? Is there any way to tackle the issue or check the status of the speaker?
