If you go into the system Settings -> Sounds and vibration, you can set a default Ringtone, and a default Notification sound but there is no option to set a custom default Alarm sound. The phone seems to be hard-coded to use Homecoming as the default sound for new alarms, whether using Samsung's Clock app or the Google Clock app.
An intensive search reveals several formerly-working methods to change the default Alarm sound, some of which involve using certain third-party apps such as Zedge or an old version of ES File Explorer. I tried the Zedge method and found that it can't access local files. So if you can't find the alarm sound you want in the app, you're out of luck. The ES File Explorer method seemed to be working at first, but a short time later, it wasn't - new alarms were once again being set to Homecoming.
Also, other users reported that their workarounds failed after a system update or phone restart. Is it really so hard to make this audio feature work as easily and effectively as setting the default Ringtone and Notification sounds? Or do you just not care about making the user experience consistent, easy, pleasant and convenient?
