[ubuntu-mono] [Bug 1340349] Re: [Precision WorkStation T3500, Analog Devices AD1984A, Green Headphone Out, Front] equalizer problem

Thu Jul 10 20:39:25 UTC 2014

I can activate the equalizer without issue each time, but by following
certain steps I can reproduce the crash as well.

1. Run Banshee and play a CD (in my case, Babylon 5 Volume 2: Messages
from Earth but that probably doesn't matter).

1. Bring up the equalizer with Ctrl-E, set the equalizer to Rock, turn
off the Enabled checkbox, and exit the equalizer.

3. Hit Ctrl-E to bring up the equalizer again, which should show the
Rock setting.  Change it to Classical and then click the Enable
checkbox.  Notice that the music stops immediately, and bad things
proceed from there.

Also, in case it makes a difference, I just (in the past few days)
updated this machine from 12.04 to 14.04, and have never used the
equalizer in Banshee until today (that I can recall).

Here's what showed in my terminal when I did the above:

[1 Debug 15:35:10.150] Disabled equalizer
[1 Debug 15:35:12.517] Selected equalizer: Rock
[1 Debug 15:35:45.574] Selected equalizer: Classical
[1 Debug 15:35:48.361] Syncing equalizer to engine: Classical
