If that is so, then espeakup is incompatible with a default pulseaudio
configuration. Maybe this should be documented somewhere.

I'm reassigning this bug to espeakup because it should really be modified
to work as non-root as Lennart suggested. AFAICT, the only reasong for
running as root is to access the softsynth device, but that could be
managed via regular uaccess and group mechanism like /dev/snd/* does. We
shouldn't require running pulseaudio as root, as it would be better if
espeakup would run unprivileged.

I'll leave it to the espeakup maintainers to adjust severity.

[Scott Leggett]

Hi,

I've been able to reproduce this bug. A not-very-helpful workaround is
to restart espeakup whenever sound goes missing.

I've dug into the issue a bit and found it discussed on
pulseaudio-discuss back in 2010. The discussion on the thread seems to
indicate that espeakup and pulseaudio couldn't coexist at the time due
to espeakup not being multi-seat aware. Lennart summarised what needs to
be done to get them working together[0].

I'm not sure what the situation is now. Looking briefly at espeakup
upstream [1], it doesn't seem to be very active, so maybe the situation is
the same?

ESpeakup is running as root, and everything is running as a user. I think the 
easiest solution here is to configure Pulse to run system-wide. I know there 
is an option in one of the Pulse configuration files to enable this, but I 
don't think Debian ships a startup script or systemd service file to use 
PulseAudio in system mode. Happy to be corrected.

I am very much ignorant about how screen readers work. Could you describe a
bit how the stack works please? In particular, what program is actually
responsible for playing the synthesized speech to speakers, and how does it
run? Also, the audio-related configuration (if any) of these programs would
be useful.

It sounds like the programs that play the speech to the speakers are
grabbing the sound device and not letting it go - thus making it impossible
for the alternative programs to actually play the sound.

Some information that would be useful:

1. Is your user part of the audio group?
2. Does any of the programs that actually play the sound run as root or a
user that is in the audio group?
3. Please attach the output of `lsof /dev/snd/*` for each of the
problematic states (this should answer question 2).
