Yikes! I did another inexplicably short unexplainable mail! Anyway, I don't have much info on this, all I know is that with my AWE64 is very good at helping to hang my machine. I've tried to use rosegarden a few times so far, first I tried the Randall Hopper's awedrv-0.4.0a (I'm not too sure about version numbers here), and that caused me no end of problems as far as pcm sound was concerned however I had some good midi sounds through the card and I was able to load soundbanks - happy for a while! I got Sujal's PNP patches (FreeBSD-ISA-PnP-June08.tgz I believe ?) and GUSPNP15, I'm running 3.0-970618-SNAP, which seems stable enough in most cases.. but here's a list of the problems I've got now: [Quake : Nothing caused by sound, xf86quak occasionaly dies horribly (freezes screen but doesn't actually shut down) when I try and quit, but I assume this is just poor Xdga programming - any ideas on this ?] cat mysound >> /dev/dsp occasionaly seems to come out slightly slow (I've tried options BROKENSB, but it doesn't help - rplay doesn't have the problem, so I gave up worrying about this.) I think this was happening with this as well cat /dev/dsp > mush cat mush >> /dev/dsp Also reading from /dev/dsp too quickly can cause a panic. e.g. any user can open /dev/dsp say O_RDWR | O_NONBLOCK, read and write tons of stuff direct to the device and panic the machine. [ found this out while hacking some stuff together really badly =) ] I'll check on some of the other problems I had when I was at home, but I found out most of them while on holliday, by the time I was going to say something we're onto guspnp20 and I've forgotten half the problems. I do have a fair amount of code with warnings which say "don't run me, it'll panic." That's mostly my fault I expect, although I was developing as joe luser, no special priviledges.
