I'd been listening to the BBC radio with realplayer, stopped realplayer, then opened the BBC's iplayer which uses flash in Firefox. Played the BBC stream for a bit in Firefox (which is terrible dues to the flash stream requiring more bandwidth than my dialup connection can deliver), then stopped the iplayer, also closing the tab for it, and tried to start realplayer playing again, without success. I had to close firefox completely before flash would let go of /dev/dsp. Only after that would realplayer work again. Try the line below when you've used flash, and can't get other sound apps to play afterwards. It will tell you what is grabbing the soundcard. /usr/sbin/lsof -n | grep /dev/dsp The problem is that most soundcards are only able to play sound from one app at a time, unless you have an audigy2 soundblaster card which is capable of hardware mixing, and dealing with multiple audio streams. Saying that though, dmix is supposed to be able to deal with multiple sound apps on other cards. I think that flash may be the exception. Leaving flash out of the equation, I have no problems with other apps failing to release the soundcard when I stop the app. and I mean just stop the app playing, not closing it completely. for example, I can play something in realplayer, stop it, then play something with mhwaveedit, stop that, and start playing realplayer again with no problems. That's on my very old FC2 install, which machine has an Ensoniq (ens1371) soundcard. Apologies for Sunday afternoon ramble.
