Help Can't control Gmails notification tone

[michaelcfb]

For some reason the Gmail app on my phone ignores my default ringtone, and instead chooses to have a piercing old-timey phone ring. It has no internal control to set specific tones itself.

How can I get the gmail tone to change? My normal mail makes a pleasant tone, as do my SMS messages. It's only gmail that's being a jerk!

Thanks,
Michael
