|Sound stuttering on Acer TravelMate 4200 laptop
Having searched all the forums and extensively on Google, I have not yet found a solution to this annoying problem...
When playing any kind of media from any source, after a short time, the output stutters until the mouse is moved. Constant mouse movement prevents the problem. Stop the mouse and within a short time, the stuttering starts again.
This system worked fine with Ubuntu 10.04. A clean install of 12.04.2 with all the latest updates gives rise to this problem. Also does the same with UbuntuStudio and ArchLinux.
I have two identical laptops doing the same thing.
Acer TravelMate 4200 V3.24
3.2.0-38-generic-pae GNU/Linux i686 SMP Enabled
Driver version: 1.0.24
Library version: 1.0.25
Utilities version: 1.0.25
Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02)
Modprobe options (Sound related):
snd-cmipci: mpu_port=0x330 fm_port=0x388
Any ideas would be appreciated as my arm is getting tired from waggling the mouse.....
