This system is not completely up to date.
Please remove these lines in /etc/asound.conf
pcm.default pulse
ctl.default pulse
or just remove the file.
Also, speech dispatcher should now be at version 0.8.8, so check in
/etc/slapt-get/slapt-getrc that you have exactly this line:
SOURCE=http://slackware.uk/slint/x86_64/slint-14.2.1/:PREFERRED
then to get the updated package type:
slapt-get -u # just in case
slapt-get -i speech-dispatcher
As an aside, I tried to use libao as audio backend of speech-dispatcher
and I get better results that using alsa directly.
This confirms what Halim Sahin posted today on the orca mailing list in
response to a post from Janina (and what already told me Samuel Thibault
or Kyle IIRC).
But I will do more testing before uploading an updated package and
anyway you should already get better settings doing what I wrote above.
Best,
Didier
