Bug Description
Distro:- Ubuntu 12.10 Quantal,
What I suspect is that sound is muted and turned on at a fast pace and that gives it the choppy sound. I discovered that If I choose Sound Card ;- Mixer - HDA Intel - the surround sliders show mute/on at a fast rate, with
- do - Mixer - Play back: Build in Audio Analog Stereo - the master sliders jumps up and down rapidly a short distance.
I find the same happening on U tube. Movie Player with videos not so badly affected.
Following is reports that I thought could help to pin point problem.
If more info needed, I would gladly provide such. Still new at this so please bear with me.
Thanks in advance for help that I know would be forthcoming.

I found the following link on the net, "http:// forums. linuxmint. com/viewtopic. php?f=42& t=44862" tried what was suggested there and it sounds better. config( etc/pulse) file
Some value adjustments to daemon.
default- sample- format = s16le sample- rate = 48000 sample- channels = 2 front-right
default-sample-rate = 44100
; alternate-
default-
; default-channel-map = front-left,
default-fragments = 32 fragment- size-msec = 50
default-
I hope that this will help to give a better perspective on the problem.
Failing that, will it be safe to remove PulseAdio completely and run with Alsa only, I am on UbuntuStudio and are scared it will break "Jack". Any suggestions?
