Example sound file which is affected by this problem.
Description of problem:
After installing the latest batch of system updates, some sound files are not played correctly, unless I open a PulseAudio Volume Control window in the background. Then these files are audible OK.
It does seem to affect Totem (with gstreamer background) and applications like Pidgin, where I have custom wav file set up to indicate new messages (attached). However, Rhythmbox seems to be not affected by this issue.
Version-Release number of selected component (if applicable):
[root@m4300 ~]# rpm -qa | grep pulseaudio
Try play attached file with Totem. File would seem to be played OK, but there is no sound. Then open PulseAudio Volume Control window and try again. It will sound OK.
Steps to Reproduce:
Can't hear any sound when PAVC window is not open.
Sound file should played nevertheless of PAVC window.
It does happen on two different machines, both after installing the latest system updates.
As stated above, however, it does not seem to affect Rythmbox at all.
I can confirm this bug on my machine,
attached file is audible when PulseAudio Volume Control window is open only.
it may be related to another bug I've spotted - when I play movies / videos, first couple of seconds are quiet and or with noise and crackles, then audio is fine. I've just tested and when PAVC is open, there is no silence / noise or crackles when video playback starts.
I am pretty sure this got fixed in F11 (0.9.15) . Closing now. If it didn't get fixed, feel free to reopen.
