Hi Steve
No, that's not the issue in your case. The volume bug exists when
espeak outputs to Pulse, however speech dispatcher doesn't use
Espeak's output routines. Sd interfaces to Pulse directly, uses
libespeak to synthesize, then outputs the synthesized data itself. I
haven't had any volume instabilities with speech dispatcher and
Pulseaudio, but I did recompile speech dispatcher with pulseaudio
support (the default Arch packages do not have it unless it was added
within the last week). Did you recompile speeech dispatcher to have
Pulse support? If not, you might be trying to use it through the ALSA
plugin, which can create all sorts of wacky problems.
As for OSS4, I wish it had lived up to what it could've been. The API
is simpler, it's quick and responsive, and has a much better output
routine than ALSA. Unfortunately, most of OSS4's drivers are buggy
beyond belief, and USB microphones aren't supported at all. If you've
got one of the cards which has a stable OSS driver and don't care
about USB input, you can use it. I'm not so lucky, unfortunately, and
all of the stable OSS4 cards have long since been discontinued.
