Rdio: sound is muted at startup and doesn't match per-application system volume

[Shaun Viechweg]

Nuvola Player 2.0~unstable555
Ubuntu 12.04
These might be 2 separate issues.

The first issue is that Nuvola player (Rdio service) starts with the sound muted (turned all the way down).
The sound in the Rdio service starts maximally, but navigating to the sound settings menu (Settings > Sound) and then the Applications tab shows Nuvola player turned all the way down (within any user input). Turning it up manually restores sound as expected.

The second issue involves adjusting sound. Changing the sound outside of Rdio (via Settings > Sound > Applications) does not reflect changes within Nuvola player (the slider doesn't move but the volume is changed. I think this is normal). However the external slider is automatically set to the level within Nuvola player upon next interaction with the player or next song change. For example, if I set the external slider to full volume while the Nuvola/Rdio slider is set to 50%, volume increases to match the external slider. However the next time I click on Nuvola Player (or a song change occurs), the external slider is automatically set to that of Nuvola/Rdio and sound then decreases to that of the Nuvola/Rdio slider.

Expected behavior would be to perhaps mirror slider and volume changes both within the player and within the Settings menu.

Thanks for taking the time to report this bug. I've subscribed maintainer of Rdio integration.

Stefan, can you reproduce the issues? What does Rdio use for playback? Flash or HTML5 audio? (See bug #1026721.)

[Jiří Janoušek (fenryxo)]

To investigate this bug further, I need to know whether Rdio uses
Flash plugin or HTML5 for audio playback. Could you run following
command and report whether Rdio is able to play music?

nuvolaplayer -D --no-web-plugins

[Shaun Viechweg (stump86)]

running the above command, nuvola is able to play music after adjusting the volume.

Are both issues reproducible in WebKitGtkLauncher?

/usr/lib/webkitgtk-3.0-0/libexec/GtkLauncher \
--enable-plugins=false http://www.rdio.com/

[Shaun Viechweg (stump86)]

They are both reproducible in WebKitGtkLauncher.

I've uploaded a video of my problem to youtube and attached it here as well. The sound I hear follows the level as set in the sound menu GtkLauncher slider, not what is displayed in the rdio window. So I don't hear anything until around 41 seconds into the video although the rdio slider starts at full volume (0:20 - 0:40).

Adjusting the rdio slider has no effect on the gtklauncher slider or volume I hear until the gtklauncher slider is umuted (note it starts muted) (0:47 - 0:52)

Adjusting the gtklauncher slider has no effect on the rdio player slider but does affect the volume i hear (0:52 - 1:01)

The issue seems to be caused by a bug in WebKitGtk then, so it's
necessary to get in touch with WebKitGtk developers. Could you create
a bug report at WebKitGtk bug tracker and post address of that bug
report, so I can subscribe to it? See
http://trac.webkit.org/wiki/WebKitGTK#ReportingBugs for help.

WebKitGtkLauncher starts with sound muted (at the system level) and doesn't reflect changes to volume made within the WebKitGtkLauncher. Specifically for website http://www.rdio.com. Once unmuted (through manual adjustment in system volume) sound works as expected i.e. changes made in WebKitGtkLauncher are reflected in system sound levels.

I was just browsing through the bugs and saw this one. I have noticed this in the past, but not as much recently. Although, I have customized my integration to use flash. While audio playback via HTML5 works, I don't believe it is the supported/suggested playback method as it is not as stable as flash. Other issues I observed without flash included having to reload the page every once in a while because the next track would not load.

I would suggest changing the integration to require flash regardless of the affect it may have on this bug as it is much more stable. From what I've seen, Stefan does not really seem to be actively supporting this integration anymore. I would be willing to take over integration support if that is acceptable.

Sure, go for it.

After much testing, the problem appears to be with the AudioFactory of the Rdio client side js and not with WebkitGTK.
