where to open the sound since there is no sound while making a music

If there is no sound while making music, the issue could be with the equipment or software being used. Here are a few steps to troubleshoot and potentially fix the issue:

1. Check the volume levels on all devices being used, such as speakers, headphones, and any audio interface or mixer.
2. Make sure the audio output is set correctly on the device being used to make music (e.g., computer, tablet, phone).
3. Check the connections between all devices to ensure they are securely plugged in.
4. Verify that any software being used to make music is not muted or set to a low volume.
5. Restart all devices and software being used to see if that resolves the issue.
6. If the issue persists, try using different equipment or software to determine if the problem is isolated to a specific component.

If none of these steps solve the issue, it may be necessary to seek assistance from a professional audio technician or support from the manufacturer of the equipment or software being used.
