Re: No sound on youtube
No, FF+Flash is not in KDE. I thought that Mozilla disabled flash after updates and installed mozilla addons to get choose between Flash and HTML5. But with HTML5 enabled youtube didn't want to play any video. I returned to Flash, installed h264 codecs and found that I had lost sound at all. After this I saw into KDE settings, in sound. I have to notice, that's two device to choose I have in sound settings - first one is really something about sound output from motherboard, and second one - HDMI (I don't know, if it's possible to get sound output via HDMI), by default was choosed first one, and it has drop-down menu with 15-20 variants, here was choosed input instead output, it first. And second, clocked on sound label on KDE panel, it shows menu, that has two tabs - system sound and applications sound. I don't know why (possibly it's a normal thing) but mozilla had several sound bars (probably, mozilla represents sound in OS by separated "threads" as it's represented in FF via tabs, allowing to mute sound per tab) and one of bars had slider turned in 0%. Sorry for many letters, tried to describe all things, maybe you have similar problem in Gnome.
P.S. FF works with Flash by default. You can try to change it's behavior via addons, and don't forget to check Flash permissions
