Description Gary Cramblitt 2006-01-08 18:54:23 UTC

Version:           0.3.5 (using KDE KDE 3.5.0)
Installed from:    Compiled From Sources
OS:                Linux

With ALSA v1.0.10 or ALSA 1.0.9-8, duplicate this problem as follows.  Configure ALSA as output audio plugin.  In Job tab of KTTSMgr, click Speak Clipboard.  While sentence is speaking, click Remove.  KTTSMgr freezes because kttsd is frozen.

ALSA seems to have changed its behavour sometime after 1.0.8.  It used to be that calling snd_pcm_drop on a playing pcm would cause an error and stop the playback.  No longer.  Instead, the code in AlsaPlayer::stop() calls snd_pcm_drop  and then waits infinitely for the playing thread to exit.
