I'll preface the following by saying that this is only an outline of my recent experiences and others may not have as much luck. Issues, such as sound card type and manufacturer, ALSA driver support etc, means there can be a lot of variation in this area. A while back, I posted to this list regarding the success I had achieved with espeak and pulse audio. I reported that I'd found that the emacspeak espeak driver, compiled with portaudio support did not work well. It was sluggish and had a tendency to chop off ends of words or skip words. I found that re-compiling it against pulseaudio rather than portaudio fixed these issues. At the time, despite numerous different strategies, I was never able to get good quality ViaVoice outloud output with pulse audio. In fact, I had never been able to get good quality outloud output without customizing ALSA via a .asoundrc file. Recently, I have upgraded my system to Ubuntu 11.04. I decided to re-examine matters and see if I could get a better outcome. One problem I had with the existing setup was that when running emacspeak and the outloud server, pulse audio was blocked and so I could not run any app built with pulse audio. Given this was an upgrade and had lots of new libraries, my first step was to remove all alsa and pulse audio configurations. I removed my .asoundrc file and restored all pulse settings to their default, rebooted the system and then started playing around to see what I needed to do to get as much working as I could. The outcome was surprising. For the first time ever, all my sound related systems on this desktop are working 'out of the box'. I have Outloud running via pulse audio, can run multiple sound sources, both pure ALSA and pulse audio systems simultaneously and have full control over each independently of each other. The system I am using is a Dell 32bit desktop with an internal 'on-board' soundcard from Intel. I'm running Ubuntu 11.04. This system has been running Ubuntu since 8.04 and has only been upgraded and not re-installed since its original setup. Looks like Linux sound support is really beginning to mature and provide similar functionality to what is common on other more expensive and locked down solutions.
