Hi
Getting espeak to switch cards was no problem. I just told Pulseaudio
to direct espeak to my USB speaker and that did it. I used pavucontrol
from within GNOME to do it, but I believe you can do it through pactl
as well. That's one reason I like using Pulseaudio, I can direct audio
where I want it regardless which program is generating it.
I haven't gone into the espeakup source yet, but I notice that
espeakup depends on libasound. That would suggest to me that espeakup
is not actually having espeak do the audio output for some reason, but
is interacting with ALSA directly at least for part of the process.
Your issue plus mine insisting on always opening the first card
regardless of what I tell ALSA to do would indicate this. Your issue
about invalid sample rate suggests that espeakup is trying to output
to the same card that Pulseaudio is currently using.
