In Ubuntu, The flash player and Rhythmbox sound conflicts solve the problem that flash playback has been a problem since ubuntu was installed. When firefox3.0 comes with the system, flash cannot be played, not without sound, that is, it cannot be put, it can be put for a while, and it cannot be put for a while. It is annoying. Later, I simply deleted the built-in firefox of the system and went to the firefox official website to get the latest one, decompress the package and use it. Ah! It's really good. flash can be released at last. It's so nice. I can watch the video at last, saving me a lot of effort. However, it was not a long time. Later, I found that after each flash, I could not play the music with the system's built-in Rhythmbox. I could not play it anymore. I had to restart it before I could play it again, but the music was enough, flash cannot read it again. Fainting .... No one is really worry-free. I couldn't search for it online. It worked really well and solved the problem. The following is a solution to the problem: Note: This method is only used in the gnome environment of Ubuntu 8.04 to solve the problem that firefox flash player and Rhythmbox cannot simultaneously sound. You can use the new software manager to install and delete software packages. Step 1: 64-bit/AMD64: Install Getlibs related installation packages including: getlibs-p libnss3-1d; getlibs-p libnspr4-0d; getlibs-p libcurl3; getlibs-p libasound2-plugins; under 32-bit/i386: delete the following installation packages: nspluginwrapper; libflashsupport; delete the related configuration files: sudo rm ~ /. Pulse /*~ /. Asoundrc */etc/asound. conf step 2 install the following package and related dependent packages: padevchooser; libao-pulse; libasound2-plugins; libsdl1.2debian-pulseaudio step 3 run the following command on the terminal: asoundconf set-pulseaudio echo "default_driver = pulse"> ~ /. Libao step 4 set sound: in system-preference-sound, set "sound playback" to "Automatic Detection" step 5, log out, and log on. OK! All done. Both flash and Rhythmbox have sound and can be played simultaneously.
