[Notion-general] There is no sound

[Thomas A. <t.d...@gm...>]

Previously when my desktop runs with gnome (dgm3), I can hear sound
without a problem. However, after switching to use notion, I notice
that I no longer able to hear any sound from media. For instance, go
to youtube, there is no sound. The same when I play video with
mplayer.

I am sure the hardware should work ok because when switching to
windows 7, I can hear sound played from media e.g youtube, etc. Also,
alsamixer shows that volume is shown up including Master, Headphone,
Speaker, PCM, Front, Front Mic, Front Mic Boos, Line, and Mic.

What files do I need to modify?

Thanks.
