Description of problem:

1. The general system sound gets adjusted according to the sound set in the last app that played sound using PulseAudio, or, when there are more than one running concurrently, the one that had its sound last changed. For instance, if I enable window and button sounds, when those sounds play the general system volume gest adjusted according to their volume.

2. Setting up sound on per application basis seems flawed. When I move a volume slider in an application (when it plays sound), the general PulseAudio and ALSA sound levels are raised/lowered, only exponentially. I.E. if I raise the volume in e.g Rhythmbox from 0% to several %, the PulseAudio and ALSA sound levels get almost maxed out.

If the application is not playing sound, when when its volume is changed, then the general sound levels of PulseAudio and ALSA remain unchanged.

3. Sometimes the Pulse Audio volume slider in notification area stays at 100% when moved manually but doesn't affect system volume and doesn't mean it's maxed out. Pulse Audio is still running and it's volume level can still be adjusted from pavucontrol and gnome-volume-control, but the slider in notification area doesn't reflect the changes.

4. Most of the time Pulse Audio volume slider adjusts the general system volume, but in a weird manner, i.e. when it's at around 45% and below, the ALSA volume level is muted. When the Pulse Audio volume slider is turned up above that level, the ALSA volume level gets adjusted exponentially.

5. Sometimes muting an application doesn't work, i.e. there is a mute icon displayed but the app is not muted

6. See bug: https://bugzilla.redhat.com/show_bug.cgi?id=510600

Expected results:

Different applications can have different volume levels without interfering with the main volume level of Pulse Audio / ALSA or one another.

If changing Pulse Audio volume level is supposed to adjust ALSA volume level as well, those two should be streamlined. Otherwise each shouldn't affect the other.

Comment 2 Adam Williamson 2009-07-15 17:08:35 EDT
As you say, these are multiple issues. They cannot be addressed sensibly in a single report. Please split them into separate reports.

None of them fits the criteria for a bug that should block AlsaVolume. That bug is NOT a tracker issue for 'any problem with sound', it is a tracker for a very specific type of bug (as explained in its comments).

Point 1 is not a bug, it is the intended functionality of recent PA releases (it's called 'flat volumes').

Please report each of your other issues separately (and don't mark them as blocking AlsaVolume). I'm closing this report as it'd just get too messy, but this doesn't mean we don't want your reports, just please structure them correctly :) thanks!
