New version 1.3 came down last night but the same problem.
run in terminal give this

Can you run kazam wih --debug option and attach the output?

[David Klasinc (bigwhale)]

Thanks for the report! This should be fixed in stable and unstable branch. If you can test the stable branch and report your results back, I'd appreciate it. I can't duplicate this bug, so there is no way for me to test it.

[Chris Giltnane (chris-giltnane)]

Will do as soon as I get the update
Thanks

[David Klasinc (bigwhale)]

Awesome. It would be most helpful if you can test this on new stable version - 1.0.7.

[Chris Giltnane (chris-giltnane)]

Have not been able to update yet but have found the cause of the problem. I had the input microphone volume for both the internal mic and the docking station mic ( which I have not got) in the sound preferences set to mute. As soon as I changed that to a low level but not 0 level kazam started with no issue, hope this ties in with your fix

[Dion de Ville (diondeville)]

I can confirm the bug still exists and the solution is the same as Chris mentioned, above. the input device streams do not need to be muted, just put to as low a level as possible.

Glad I found this solution because I uninstalled, purged, tried different PPAs... Chris, thank you for your solution. David, thank you for this software, it is awesome.

[David Klasinc (bigwhale)]

Apparently this bug popped up in two different places in the code. I've tested it in stable and unstable branch and I can't reproduce it in the stable version. Which probably means that the intial solution fixed it for stable branch. Unstable branch is working with volumes a different way so another fix was required.

Thanks for all the info. I commited the fix and you can try the unstable branch again.

[David Klasinc (bigwhale)]

Steps to reproduce this behavior:

- open pavucontrol
- set volume of all the input sources to the lowest level
- start kazam
- you should encounter a ValueError exception
- apply fix
- restart kazam to confirm there is no ValueError exception

[Chris Giltnane (chris-giltnane)]

Unstable now works for me. Thanks

[David Klasinc (bigwhale)]

Thanks! Awesome.

[Paddy O'Reilly (r-launchpad-smallroomstudios-net)]

I encountered this issue after downloading Kazam from 12.04's default repo. Chris' solution fixed it.

[Vadim Peretokin (vperetokin)]

I ran into this problem while being subscribed to the stable PPA (I noticed it's mentioned that the unstable one does not work). Had to set the input mic to be above 0db as well:

It's be nice to have a patch to the stable PPA fixing this, because PA will randomly set the input mic to muted for you, without your permission or will.

[Jack Wearden (jackweirdy)]

I'm still experiencing this bug, and Chris' solution of making the input volume non-zero fixes this for me

[Jack Wearden (jackweirdy)]

Looks like on app.py line 578 audio2_vol is -infinity, I've fixed it locally by prepending with the line:

if audio2_vol < 0: audio2_vol = 0

[Jack Wearden (jackweirdy)]

After branching from lp:kazam, the code is different to what I get from running apt-get source kazam. I don't know enough about Ubuntu packaging to figure out where the repo is for the code being installed.
