This is a really weird bug. I upgrade my ubuntu version to 8.10. Since then i am experiencing problem with my ALSA sound. If i go to setup my sound card to play with alsa i get this error on the test "audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample ! gconfaudiosink". So i changed this to OSS.
In addition to this problem came the sudden loss of shockwave flash plugin on mozilla which enabled me to view youtube videos. So reinstall a new one and now i can see videos but some weird things are happening.
1)The firefox is eating alive my CPU. I mean is impossible to even have tab browsing when the youtube video is playing
2)Because of this CPU loading if the youtube videos has spikes and frame is not even 10frames/sec
3)After a while the sound get lost(this is probably because of the cpu loading im guessing or the is because of OSS)
As you can understand this makes totally useless the flash plugin on mozilla..any ideas?
UPDATE: I installed flash on opera browser and it works fine. So i think that this is a mozilla problem.
Also i ended up on having now 2 shockwave flash plugins on mozilla with no clue how to remove them. the first is 9.0 r100 and the second 9.0 r124 (which doesnt work).
UPDATE2: So i did a little more experimentation and i found out that if i delete the file that was in here
/usr/lib/swfdec-mozilla libswfdecmozilla.so the old buggy version dissapeared from firefox so now i have only the 9.0 r124. It works like charm except the thing that i dont have a sound.
