Loss of sound in Thunderbird only


I’m running Thunderbird 2 (latest), Suse 11.1 and KDE 3.5. I keep up to date on everything and am current as of 7/27.

Before I updated the machine this morning, I noticed I lost the notification sound on Thunderbird. The wav file itself is fine. Everything else with sounds works, KDE start, stop etc., sounds from videos, VLC, etc.

Anyone else have this or have an idea where to look to fix it? I have powered down the machine, re-selected the wav file in Thunderbird prefs with no luck.

Any help would be appreciated, thanks in advance.
