The 'chipmunk' issue with Logitech webcams

  I have a C310 Logitech webcam and using some applications, other meeting participants complain that my audio sounds like that of a 'chipmunk'. After some googling the issue was identified to be the wrong sampling frequency identified by the camera.

$pacmd list-sources for this;

name :alsa_input.usb-046d_081b_2B075230-02.mono-fallback

   sample spec: s16le 1ch 48000Hz

this must be set to 16000Hz in /etc/pulse/default.pa

load-module module-remap-source master=alsa_input.usb-046d_081b_2B075230-02.mono-fallback rate=16000

which will show a remapped device, like(from pavucontrol)

 that should fix the issue.

arm_freq above 925, results in instability.

Will the U.S invade Iran and if Yes, when?

The Iran invasion will not happen till the Syrian leadership becomes US friendly and allows US forces to use Syria a military base. Waiting on Russia to cut a deal with the US for this to happen.

NAM is NAN - Non-aligned movement is Non-aligned No more. With many of the emerging powers except China, finding themselves with an opportunity to have a bigger say in world politics, a world still largely controlled by the West, the stage is set for a Muslim .vs. Rest of the world show down. I don't think it will result in an all out war, but just in case, you are buying gold right?!
