The Problem:
Using native Mozilla and linuxpluginwrapper/linux-flashplugin (on 4.10-stable et al) to view flash content results in no sound and occasional Mozilla freezes.
The Solution:
Run esd.
How:
I was searching the web for the solution, and got nowhere. There didn't seem to be anyone who had gotten it to work. Linux mailing lists noted a problem with file permissions on /dev/snd or /dev/pcm* depending on the sound system drivers installed. My /dev/pcm* file permissions were all rw to begin with, so this didn't help.
I wondered what device the plugin was actually trying to access, so I did "strings /usr/local/lib/linux-flashplugin6/libflashplayer.so" and found /dev/dsp and /dev/mixer. Nearby in the list I noticed a few lines relating to esd. From a command line I started esd and went back to view some content that had previously frozen Mozilla, and there was sound coming out my speakers and the browser did not hang.
I had long suspected the browser hangs were related to sound in the flash content. My results seem to confirm that suspicion.
Do you have an example (or two or more) of a page that causes the crash? I'd like to test this on 5.3-R. I know I used to have an email around here somewhere with examples ...
Speaking of flashplugin crashes: There is some flash content out there which makes my firefox crash (not due to sound but for some other reasons). One example is:
http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&item=5961030392
I'd like to know if other people also experience crashes when viewing this page. The flash content isn't obvious to find: When the page has opened search for the string "Setzen Sie die Andale Gallery". Directly above is the flash part. I can only view this page when disabling the linux-flashplugin :-(
Thanks,
-Andre
That worked ok for me without crashing. One site that I know always crashes my browser is this one: http://www.flickr.com/photos/
Just click on any of the photos there and the new page will load up and crash. If anyone cares I have attached the backtrace from the crash below.
This is what I have installed:

I have been bad at updating this month so I may be behind in ports and this has already been fixed.
