I noticed it happened while launching Mail, iChat, Adium, Skype and Safari just after the boot process completed, but I was unable to reproduce it by launching the application in a controlled way, one by one.
I forgot to write that the device selected in Cog was NOT the standard output, it was a composite device I created with "Audio MIDI Setup". The device is made of Soundflower2ch and the Standard audio output, joined together.
I also forgot to write that the bug makes Cog switch back to the standard output as defined in the system preferences, even if the cog preferences still show my device as output device.
