Description of problem:
On AC97 soundcards (most PCs), there is no hardware mixing. Any firefox plugin that uses the kernel OSS emulation layer may hang other applications that want to use the sound device, regardless of whether or not their asoundrc file is set up to use dmix. This is problematic when people are using web radio (such has BBC On Demand http://www.bbc.co.uk/radio/aod/).
Recommend that LD_PRELOAD=/usr/lib/libaoss.so is added to the firefox script so we can use the userspace OSS emulation. Doing this will give a better user experience, akin to what one might expect on Windows or Mac OSX.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Use RealPlayer plugin in Firefox
2. Attempt to use mplayer, totem or any other media player
Actual Results: Other media player hangs.
Expected Results: Should have simultaneous playback
