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. Lee
