this is because flashplayer uses alsa directly (not pulse audio).

It can be solved by redirecting default alsa device to pulse. It's included
in my asound.conf (see wiki). But remember that this will not work on AMD64
unless you manually upgrade flashplayer to true 64bit version (see wiki).

Bug description:
Reporting this bug for another user...

In MacBook and MacBookPro 5,1 (aluminium, late 2008) the soundcard works out of the box only with headphones, and to turn speakers on it is necessary to manually set the 6 channels. In that case, sound is heard both on headphones and right and center speaker; the left speaker doesn't work yet.

This bug is confirmed by several users, see the additional information attached.
