I downloaded and installed the latest Gnash from CVS and it is blazing fast on my FC5 x86_64 manchine. I showed it to some friends, which I'm trying to convince to switch to 64-bit Linux, but when they asked me about the sound support in Gnash, I couldn't answer, so I thoguht I'd ask the ones responsible for the strides Gnash has made in supporting flash under *nix natively and, most importantly, Freely (as in freedom), how is sound support going?
I understand there are a lot more stuff you might be working on, like ensuring better swf support, improved support for Flash 7 and a lot more, which might or do take precedence to proper sound support.
By the way, kudos to all involved, Gnash is coming around impressively. It is much, much faster than the propietary flash palayer, and the use of OpenGL for drawing, really shows! (my card has the inconvenience of starting its fan whenever it's used, and Gnash makes good use of it :))
