Problem: I just discovered that thunderbird 52.4.0 (64bit) on Ubuntu Xenial can't play a wav file for new mail. The default new mail sound can be play though.
Solution: I installed "Sound Converter" from Ubuntu Software and used it to covert my .wav file to .ogg format (mentioned by @doxland) and tried it on Thunderbird. It works... :) Thanks @doxland for sharing about .ogg format. I did not know such a sound format had existed. Hope the Thunderbird team could make this fix seamless or at least inform user to use only .ogg format sound file in Thunderbird. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/292676 Title: Thunderbird doesn't play any sound on notification To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/292676/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
