Set Alarm Volume Separately auf Huawei
On Huawei phones running EMUI, the alarm volume is controlled by its own slider, independent from the ringtone and media volume. This is why raising your call volume has no effect on how loud your alarm sounds in the morning.
The setting lives inside the sound settings of the phone. Open Settings ➔ Sounds & vibration, then find the alarm volume control and swipe the slider left or right until the level fits your needs.
Why the volume is separate
EMUI keeps alarm, ringtone, and media volume apart so that muting your phone for calls or silencing notifications does not automatically silence your alarm. This is intentional and prevents you from missing an alarm because you turned down another sound category the night before.
If your alarm still does not sound at all, check whether the alarm itself is enabled and whether a Do Not Disturb or Focus profile is running, since some of these modes can additionally affect whether alarms are allowed to play a sound.
Adjusting the slider only changes the volume level. It does not change the alarm sound itself or the vibration pattern, which are configured separately inside the alarm clock app.
