Playing flash videos (youtube and standalone flash) gives me choppy audio and video.
It seems intermittent, I was playing youtube videos earlier with no problems ... now I can't.
Using:
Could anyone offer any advice? Thank you.

I have experienced this too. Everything works fine but after a period of time, the sound becomes choppy in flash videos.
Restarting pulseaudio worked for me. To kill pulseaudio:
pulseaudio -k
To restart pulseaudio:
pulseaudio -D
Another way to do it, but you would be setting pulseaudio to be run a system wide daemon.
To do this, in /etc/default/pulseaudio, set:
PULSEAUDIO_SYSTEM_START=1
Then run:
sudo /etc/init.d/pulseaudio restart
What I tried in the same situation was:
In the end, I used the DownloadHelper addon to simply download the video (but that is of course a VERY ugly solution for only a few use cases.
Some people in forums suggests to right click->settings->display and disable hardware acceleration.
Disable hardware acceleration by right clicking in flashplayer window >settings>un-check hardware acc. I had terrible playback and frequent crashing in both chrome and firefox. Was impossible to watch anything. Simply right clicking and on the flash player and disabling hardware acc. FIXED jerkiness right away. Now seems playback smoothness depends on CPU load. TRY FIRST!! Less crashing already.

I had the same problem with choppy audio and video. I ended up downgrading to flash player 11.1.102.63 64-bit, which you can find at adobe's archived flash players page
Try using the alternative Flash player:
sudo apt-get -y install browser-plugin-gnash
If your video shows blueish, right click the video and click Settings. Turn off video acceleration.
I hope I understood your problem and my answer helped! Good luck!
Chopping audio usually is the results of 2 things...
1)faulty hardware acceleration support for flash player. If that is the case just disable it as indicated above.
2) aggressive cpu power throttling. To diagnose that:
sudo apt-get install cpufreq-utils
and
sudo cpufreq-selector -g performance (this will change the cpu throttling governor from "ondemand" to performance.
Now check to see if your problem is fixed.
Also... cranking up the sound quality settings in pulse audio might also help:
sudo nano /etc/pulse/daemon.conf
Scroll down where it says default-sample-rate and change it to 48000 (dont forget to remove the semi-colon !! ) Also if you have a relatively good cpu you can improve the audio quality a little more by moving a few lines up, to the "resample-method" line and change the speex-float number to 5 . Ctrl+o and ctrl+x to save and exit. Restart pulse audio or the whole system for the settings to kick in.
After trying jlynch's suggestion and getting "Daemon startup failed", my solution was to follow the instructions here to disable timer-based scheduling and restart Pulseaudio.
I am on Ubuntu 14.04 w/ flash 11.2.202.406.
Actually this is silly but have you tried with lower volume? I got the same symptom. Just to emphasize, the symptom was not distorted audio, it was choppy (mute/unmute type of effect). And as many songs have an in crescendo structure, the song will start fine and will get choppy. That was my case.
If that solves it, you may simply lower the volume control (the bar in the sound controller to 100%, not the volume per-se, although both are related).
