I have similar problems in CentOS 5. I disable and enable the flash plugin in firefox, and it seems to be corrected. My problem may be slightly different, but this is how I 'fix' the problem.
Same here, flash locks out the audio... mplayer gives me: Can't open audio device /dev/dsp: Device or resource busy Closing my browser fixes it... Maybe I should try with ALSA or ESD instead of autodetect which seems to choose OSS...?
