One of the annoyances with my desktop system is that sound in Flashplayer 9 does not work. Or rather, did not work until today. My setup requires OSS and for whatever reason the normal libflashsupport.c code does not work. I also use PulseAudio (fantastic system, you should try it) and noticed they have experimental support but for a more recent release than what is in Gutsy. I stumbled across an older copy which is compatible with the version in Gutsy (deb packaged by CJ van den Berg). The result: sound from flash using Pulseaudio and OSS in Gutsy! Happiness abounds!
