Hi Raman, I will experiment with past revisions and try to identify the 'best' version. Note that I've been using the 'previous' version (previous to recent changes) for quite some time under pulseaudio with no significant problems apart from outloud segfaulting a few times a day. For me, the responsiveness was only a little less snappy than it is with the recent updates and did not suffer from the repeated utterance artifact issue. The main potential advantage of the recent changes was that it appeared to make the server more stable. Bart, I believe that if you add a .asoundrc to your home directory, outloud will use native alsa and not use pulseaudio. However, you will run into device contention if you have another device trying to access the sound hardware, so make sure all other sound apps are stopped. I will post the output from the 'good' version in case that can help with diagnostics etc. However, I may not have access to do this until Monday. Tim T. V.
