Distorted audio ¶
Difficulty understanding the device's audio.
Earphone jack is experiencing malfunction. ¶
If audio is unresponsive, it might be related to loose wiring or a faulty jack. Test audio through the tablet speakers, then test it using earphones. If the audio is only distorted while listening via earphones, the audio jack or the earphones themselves may be faulty. Audio that cuts in and out is often a sign of a loose audio jack, so make sure the audio jack is fully inserted in the tablet's jack.

If the speaker isn't working properly, it could be because of any loose connections in the mother board. Check the board for loose wires.
