I did a Ubuntu 9.04 software update on Friday when Flash worked fine in Firefox/64 bit and MP3s played in Rhythm Box. I tried to suspend and it hung in the process requiring a hard power off to get it out of zombie mode. When I rebooted, Flash in Firefox just gives me static and crackles which appear to match the speaker's lips moving.
When I try to use Rhythm Box, I now get an error about missing a plugin. I tell it to search and it can't find the adaptive multi rate (AMR) plugin. Then I kill it, re-launch it, it still gives me the error, I hit ignore and it hangs for a few seconds and then plays normally.
Firefox still plays MP3s fine. Opera has exactly the same behavior as Firefox. MPG movies play normally with MPlayer. Sound is also normal in both Firefox and iTunes in VirtualBox -> XP. I would just use VBox except that half of my mouse controlls (everything except buttons 1 & 2) are dead and I run on 1/4 of 1 CPU (386 speed).
One other thing I did was to buy some iTunes, .m4a, songs. Perhaps loading that codec stepped on the regular audio codecs when I played them in Ubuntu.
I tried removing and reinstalling firefox. No difference. I reinstalled Rhythm Box too. No good. I re-downloaded the latest libflashplayer.so, 64 bit Linux from Adobe and reinstalled it exactly as I did to get it working in the first place. The video works, but the audio is only crackles. Alsamixer has all of the levels near max (97%) as normal.
I followed the instructions on HOWTO: PulseAudio Fixes & System-Wide Equalizer Support (http://ubuntuforums.org/showthread.p...t=streaming+tv
On system->prefs->sound, nothing works but HDA Intel AD198x Analog (OSS). There are 3 identical copies in the menu and only the first 2 work. The OSS - Open Sound system also works. Autodetect is silent as are all the ALSA and the PulseAudio.
Is there a debugging procedure to diagnose this?
