<p class="MsoNormal"><span style="font-size: 10pt;" lang="EN-US">Lets say I first send playback(tone_stream://%(1500,
3500, 440.0, 0.0);loops=100) to the channel. This will play a ring-tone
(swedish) and loop through it 100 times.. When I want to stop this tone I send
the break command, and directly after this a new playback command. Maybe 1 time
in 100 tries the tone_stream doesn’t stop playing. I think this is becuase how
break works. From what I understand from the source it just sets the CF_BREAK
flag on the channel, and then the playback application will detect this and
stop the playback. However, when I send a new playback command immediately
after break it will reset the CF_BREAK-flag again, to make sure it won’t cause
any problems for the new playback. So if the original playback (tone_stream)
didn’t check the flag before it was reset, it won’t known that it was supposed
to stop playing.</span></p>
