The error message is unfortunately a bit confusing. It means that the combination of number of channels, sample format and sample rate can not be played directly. I don't know what espeak generates but my guess is that it will play if you convert the sample rate to 44100 Hz
The newest version 1.4.16 of mhWaveEdit (not yet in Ubuntu) has support for PulseAudio, and in this version you will probably not get this error anymore. -- "file is not supported for playing" should give guidance https://bugs.launchpad.net/bugs/413759 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
