There are two situations when there is no sound in the music on the Redmi phone:

1. There is something wrong with the phone itself, or the speaker of the Redmi phone is damaged.

2. Check whether there is a headphone mark on the upper corner of the Redmi phone. If there is, it means that the phone has entered headphone mode.

If it is the first problem, you need to take it to the Xiaomi mobile phone after-sales outlet for inspection, repair and replacement of parts, etc.

If it is the second problem, you can try to quickly plug and unplug the headphones several times to see if the headphone logo in the upper corner of the phone disappears. If there is still no sound, it is recommended to go to a Xiaomi mobile phone after-sales outlet for inspection and repair or to replace the headphone jack with a new one.
