Fixing freezing and no sound youtube and flash on ubuntu
Posted by Admin • Monday, September 28. 2009 • Category: LinuxProblem:
I've had this issue for many months but obviously I don't use flash enough to really figure it out. The first few youtube videos would play, but with no sound. If you seek back and forth, or play sound from another player (eg audacious), you may get skipping sound for a little while. Eventually the whole player stops advancing, though you can still seek.
Solution:

... This will ask you for all alternatives there are for your system, but among them there will be 5-10 flash-related questions for each browser (including text browsers, apparently). Pick the newly installed adobe-flashplugin like so:
There are 2 alternatives which provide `mozilla-flashplugin'.
Selection Alternative
-----------------------------------------------
*+ 1 /usr/lib/flashplugin-installer/libflashplayer.so
2 /usr/lib/adobe-flashplugin/libflashplayer.so
Press enter to keep the default[*], or type selection number: 2
<
ul>
Software Mixing
Once I got this fixed up, I now had reliable flash playback with one little problem... There was still no sound half the time - if another audio application grabbed my sound card before firefox (eg rhythmbox). Took me a while to figure out what to search for (usually the biggest issue, right?). Apparently the issue is twofold:
- My onboard sound card either doesn't do hardware mixing, or the drivers don't support that
- Alsa should have figured that out, and turned on Software Mixing, but for some reason it doesn't do that in Ubuntu
Once I understood this, I used This page to help me out. Grabbed their ~/.asoundrc, restarted all the audio apps, and all seem to be sharing the sound card peacefully now.
