espeakup and pulseaudio

espeakup and pulseaudio

[Christopher Moore]

Hello,
I'm running archand have the pulseaudio server running.
When I start espeakup with the rc.d script, the following message repeats
each time data is to be spoken:
wave_open_sound > Pa_OpenStream : err=-9996 (Invalid device)

So what is the invalid device?

Chris

Probably portaudio trying to open your sound card using alsa but
pulseaudio has already grabbed the card and locked it open so you're
getting that error. I don't know how you'd get espeakup to work with
pulseaudio anyway since pulseaudio is typically started as a non-root user
and espeakup typically needs to be run as root so you can have speech
when you login for the first time. Espeakup would work with pulseaudio
if you built espeak against pulseaudio instead of portaudio but then
as I say I don't know how you're going to get speech in text consoles
since espeakup is started as root and the pulseaudio process is not. Yes
you can run pulseaudio in systemwide mode but if you do that the program
usually disables shared memory and so doesn't run very efficiently. Unless
they've changed some of this logic. It's been a long time since I messed
with pulseaudio so I'm possibly wrong about some or all of this but if
somebody wants to correct me then have at it. I'm not even sure how
pulseaudio helps anything over the standard dmix plugins. It's looking
like unnecessary complexity at this point but I'd be happy to try to
help get this working if somebody can give me a reason why I should
bother breaking a very nice sound setup.

The only reason I am even bothering to keep pulseaudio around is the
ability to control streams' volume independently of each other and I
seem to be getting more sound events to play now since I started using
pulse in gnome.  But I can't stand the fact that when I try to get
speech dispatcher to autosspawn properly when I startx, well that's
another matter and a very bad one at that.  I had much better luck
running speech dispatcher as a system-wide service with ALSA and then
just have Orca start up automatically when I startx gnome.  That
combination just seems to work better for me.  So, I'm about to change
speechd back to do just that.  I don't like the volume jumping all
over the place every time I restart gnome.

If you do that though you'll probably end up having speech dispatcher
crashes. I get them quite often here. I would like the per application
volume settings too but I don't want all the clipping and stuff because
the server does bad things with my PCM volumes in hardware. I wouldn't
want fried speakers possibly.

I don't know if you were replying to my message or someone else.  But
I think I will try to run speech dispatcher exclusively through ALSA
and run it as a central system-wide service like before and let pulse
do its thing when I run X.  Fortunately, my sound card (SB Live) does
support multiple channels.  As a surprise, my HP laptop also supported
multiple channels too (Realtech something or other) so pulse would be
less valuable to me except for more flexible volume controls in
gnome.  Also, I think it would be a bit of a chore to completely
remove pulse from my system now but I can avoid using it in the
console though.

Please move this other subject to a new thread!  Start by creating a
brand new message; don't just reply to someone else and change the
subject line.  Needs a brand new message to start.
