Re: speech-dispatcher 0.6.4 issue

["Kerry Hoath" <kerry@gotss.net>]

It depends on what soundcard you have and whether or not the soundcard is 
using dmix.

dmix is the plugin for alsa that mixes output streams together,
and it is part of the alsa-lib package I think or the plugins package I 
can't remember which one to be honest.

It depends on which soundcard you are using as to how many hardware output 
channels you have; however dmix is supposed to mix in software to overcome 
this problem.

Make sure your libs, utils and driver are all 1.14rc something or later 
because they changed the way they handled the plugins in 1.0.13 or later I 
seem to recall.

None of this may help; and I haven't tried to use alsa with speech 
dispatcher.
the killer will be to test if 2 oss applications can run at the same time 
with alsa;
is it a multiple open problem on /dev/dsp or is it specific to speech 
dispatcher?
Shouldn't speech dispatcher be using alsa directly and if so; should this 
not free up /dev/dsp if dmix is in use?

We need to acertain if this is speech dispatcher's fault or simply a funny 
with alsa and its plugins even if it did work before.

No idea if any of the above helps; i've had a long day at work and i'm just 
thinking at my keyboard.

Regards, Kerry.
