IndexError in Volume Control: list index out of range

Thank you for your bug report.

Do you still have this problem with the 0.4.0 rc1 version of Awn and Awn-extras ?

You can obtain this version by one of the following ways :
- Using Ubuntu 10.04 (Lucid) up-to-date.
- Using the Awn-testing PPA (https://launchpad.net/~awn-testing/+archive/ppa) and installing avant-window-navigator-trunk.
- Using Ubuntu 9.10 (Karmic) and my PPA (https://launchpad.net/~gilir/+archive/backports/+packages)

Thanks in advance for your cooperation and understanding.

Using lucid beta 1 (not updated to beta 2!):

The error seems to be fixed although volume control applet doesn't react to the volume changed in sound settings to over 100%. For example if I:
1) change the volume using applet in AWN to 77%
2) open the gnome sound settings, change it to 120% (over the 100% bar)
the volume shown in AWN volume control is still 77%

I don't have any idea how it should behave (the slider to the max and text info about the real volume on mouseover?). Tommorow I will do a clean install of lucid beta 2 and try to report the current state because aptitude shows a new version of this package.

After a recheck (by just starting the ubuntu 10.04 beta 1) the index out of range error appears again (volume was left at 120% yesterday when turning the computer off). I also checked the version of the applet, it's 0.40 rc1 (the one Julien requested).

Thanks for the feedback. Forwarded upstream.

Duplicate of #561636, which is fixed in revision 1290. Because launchpad cannot make a bug task a duplicate if it already has duplicates itself and I'm too lazy, I just make this bug task also set to Fix Committed.

@Michał Lipski: what does alsamixer tell you?

Here it is.

@Michal: could you execute the python file above and paste the output?

devices: ['hw:0']
master track: Master
volume range: (135, 255)
current volume: (152, 152)
120 0.833333333333 17
in %: 14%

@Michal: could you open volume-control.py and then go to line 542, it should currently say this:

return sum(volume_channels) / len(volume_channels)

Change this to:

return sum(volume_channels) / len(volume_channels) - self.__current_track.min_volume

I think should fix the problem you have.

Works as expected. Thanks.

Fixed in revision 1295.

@nimbosa: That is a different bug than this one. Please see bug #387437 <https://bugs.edge.launchpad.net/awn-extras/+bug/387437> for your problem (which was fixed in version 0.4.0).

Easy, just do a right click on the applet crassed, open Volume Control, and get down the volume of the system. Then restart the applet pressing it and that's all!

Please, forgive my poor English.. =D

Thanks. Good for me.
Seems like applet don't recogize volume level more than 100%.
Maybe some strings in applet code will repair this bug?

@nils: look at the status of this bug, which is "Fix Committed" -_-

I agree. I occasionally hit the bug on lucid 10.04 with kernel 2.6.35 so it's either not fixed or a new bug

As I said the status is "Fix Committed", which means the fix has been committed to the master branch in bzr. Only when the status gets changed to "Fix Released" you should be able to find new package of awn-extras that contains the fix.

This bug was fixed in the package awn-extras-applets - 0.4.0+bzr1372-0ubuntu1

kudos for this, I'm experiencing the same.
Got applet version 0.4.0 on 64bit Ubuntu 10.04

I encountered a bug too. Seems the Output volume was amplified, i.e. more than 100 %. Setting the Output volume at exactly 100% restarted the AWN applet. The stacktrace is at: http://paste.ubuntu.com/577699/

I get this error on Archlinux. It used to work, though, may be caused by an update.
