Mail lost the "swoosh" sound on MacOS 15 with outgoing emails.

Hi Apple community

I'm not so sure when it occurred as I don't send a plethora of emails, possibly though when I updated to MacOS 15.7. Incoming emails have a sound but the outbound swoosh effect is simply no longer there. There's no sound but the emails have successfully sent.

What I've checked so far:

1. Turned Focus off
2. Mail>Settings>General (only a choice for "new messages sounds").
3. Restart

So I can't seem to locate a further sound option for Mail's sent emails under System Settings for Notifications or Sounds either.

Thanks for any advice for this

Is the alert volume set at an adequate level?

Is the alert volume set at an adequate level?

Do you mean in Settings > Sounds? The alert volume is on maximum.

In Mail > Settings > General, the acoustic ding for incoming emails is audibly on maximum also.
