What you want to ask is what should I do if Music Fax A1 has noise? 1. Check the audio source. The noise may come from the audio source itself, such as a computer, cell phone, or other audio device. You can try changing the audio source to see if that solves the problem.

2. Check the audio line. Noise may be caused by bad audio wiring. You can try replacing the audio cable, or re-plugging the audio cable to see if that solves the problem.

3. Check the speaker position. If the speakers are not placed properly, noise may result. You can try adjusting the position of the speaker or placing it in a more suitable location to see if that solves the problem.

4. Check the speaker power supply. If the speaker's power supply is unstable, it may also cause noise. You can try changing the power supply or connecting the speaker to a stable power source to see if that resolves the issue.
