Ok but there will be some more changes for tuxttsdaemon.
If we want to use the same least privileges principle we've to:
- have sufficient privileges to open the ALSA channel
- drop the privileges just after opening the channel

But from this little test I can see that tuxttsdaemon
tries to open the channel only when some text is rendered.

### oops little typo to fix here: *incoming*

### now from gtdi I try to play sth:
ALSA lib pcm_hw.c:1357:(_snd_pcm_hw_open) Invalid value for card
cannot open audio device hw:2,1 (No such device)
Erreur de segmentation
### Some better error handling than core dump is welcome too ;-)

And if the channel is not maintained opened all the time but
reopened each time a text is rendered we cannot drop
the privileges :-(

There is a separate alsa channel only for tts, you could open
the channel at startup, drop privs and keep it opened.
