It's because your card lacks hardware mixing support and Flash only
supports the OSS API (/dev/dsp) which bypasses ALSA's software mixing.
The only solution is to get Flash to support ALSA natively, or get a
hardware mixing soundcard.
You might be able to work around this limitation of Flash by setting
FIREFOX_DSP to "aoss" in /etc/firefox/firefoxrc.
