My guess is that the "Generic" card is a placeholder for your HDMI audio
device, which may not be fully supported and/or not correctly
identified. Pluseaudio is smart enough to use the SBx00 Azalia device
(it has the control of card 1 open), while flashplayer blindly uses card
0 and thus remains silent. (Of course, even if the HDMI device is
supported, you won't hear anything if your monitor does not have
integrated speakers.)
Your can try to reorder the cards or disable the "Generic" one
completely. To do so, you have to unload the snd_hda_intel module and
then load it again either with
modprobe snd_hda_intel index=1,0
to reorder, or with
modprobe snd_hda_intel enable=0,1
to disable the first device.
If any of these two commands restore your sound with flashplayer then
you can make the change persistent across reboots as described in the
bottom half of this message:
