Description of problem: When playing multiple audio files in audacious, each subsequent track or file is played at 30% lower volume than the one before. Sound disappears when pulseaudio volume is below 50% (maybe another issue). Version-Release number of selected component (if applicable): audacious-1.5.1-7.fc11.i586 pulseaudio-0.9.15-11.fc11.i586 How reproducible: Every time Steps to Reproduce: 1. Load multiple files in audacious 2. Play them one after another, or change tracks Actual results: Sound volume drops by ~30% after each track change. Expected results: Playback volume should not change between tracks
I just noticed the exact same thing with XMMS using the Pulseaudio output plugin. So the problem is probably in Pulse, not Audacious. All my packages are up-to-date as of this posting.

I might be just misinterpreting this description, but I find that the audio level drops to about 30% at the start and stop, or new track. While audacious shows it's volume knob at say 70%, it seems this value has not taken effect in the gnome-volume-control-applet mixer/pulseaudio mixer. Clicking the volume slider knob, without moving it sideways sets the correct mixer value, and the audio becomes ... audible. Can you confirm this behaviour on your hardware ? maybe interesting part (not restoring volume) is: I: module-stream-restore.c: Restoring device for stream sink-input-by-application-name:Audacious. D: module-stream-restore.c: Not restoring volume for sink input sink-input-by-application-name:Audacious, because already set. I: module-stream-restore.c: Restoring mute state for sink input sink-input-by-application-name:Audacious. D: reserve-wrap.c: Successfully acquired reservation lock on device 'Audio1' I: alsa-sink.c: Trying resume...

The g-v-c-applet shows the application level disappear when stop is pressed. audacious continues to show level as 80% (or whatever you left it on). > While audacious shows it's volume knob at say 68%, it seems this value has not > taken effect in the gnome-volume-control-applet mixer/pulseaudio mixer. At play, the g-v-c-a application level stream is added to the application tab, and the value show is around 80%. Output volume~=80% as well. In pavucontrol playback:audacious level=81%, output device=81%, but audio is not heard. > Clicking the volume slider knob, without moving it sideways sets the correct > mixer value, and the audio becomes ... audible. g-v-c-a app:audacious level jumps down a 10% pavucontrol: level jumps down from 80 to 68% ==== actually with further testing I was able to see Basil's issue: level started at 68%. stop, play, lev=30%. stop, play, lev=0%. stop, play, lev=68% stop, play, lev=68% stop, play, lev=68% while typing this in, get a "no title" dialog: "Connection failed: Connection terminated, Close" box. (i think it came from g-v-c-a preferenced dialog). And it can't control, nor see the streams anymore. When it occurred, pavucontrol disappear of the screen as well. Any logs etc needed to track this down. Note: is there a possibility that running both pavucontrol and g-v-c-a | preferences at the same time will lead to pulseaudio death ?
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle. Changing version to '11'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Triaged: Reproducible also with latest updates: audacious-1.5.1-9.fc11.i586 audacious-plugins-1.5.1-6.fc11.i586 pulseaudio-0.9.15-14.fc11.i586 Using PulseAudio Output Plugin, the volume is decreased when starting Audacious or when changing track (i.e. double clicking on it), not during normal playlist listening.
The decreasing volume levels in Audacious are passed in via a PulseAudio pa_context_get_sink_input_info() callback. If volume is set to 100% in either gst-mixer or Audacious, the volume level stays at 65536. If lowered, every callback supplies smaller values. [Strangely, 50% is not 32768.] I think this is another dupe of bug 488532.
