terminal log

AIMP http://www.aimp.ru/ works perfectly on wine and I like it more than any
OSX music player, but I am having the big issue described in this video:

Basically, while the software is running on the foreground, with mouse focused
on it, the music plays perfectly for as long as I want. When the software goes
to the background (I use other programs and apps) after around 30s - 1 minute,
the sound freezes, repeating the last second of sound endlessly.

Here is another video showing quickly the problem in an even more obvious way.
When it starts stuttering and then I just mouseover on the player window, the
sound is back https://www.dropbox.com/s/9ardjn16jce51 ... 9.mp4?dl=0:

I am using currently wine 2.0rc2, installed using brew. But I was having the
same problem with previous wine versions. I tried renice for setting higher
priority to the process but it does not seem to be related with anything like
that.

I attach the messages I was getting on my Terminal window while doing the test,
not sure if there is anything relevant there.
