Dear Kingsley,
A little bit of tracking led me to discover the pause functionality in aplay
(form alsa-utils) was added last year.
This changing the old functionailty of aplay.
Takashi Iwai <http://search.gmane.org/?author=Takashi+Iwai&sort=date>suggested
a patch to preserve the old functionality while allowing the new
interactive functionality.
This patch appears to fix my hanging festival bug.
Takashi Iwai original message is at -
http://permalink.gmane.org/gmane.linux.alsa.devel/85332
Would you be able to test this patch on your aplay (from alsa-utils) to see
if it restores your festival
to working condition?
Please contact me if you need help in applying the patch for this test.
with the very best regards,
Peter
