Description grave_123 2013-01-01 14:59:47 UTC

My friend has a weird crackling that will happen on GNU/Linux Mint 14 where there's a sudden crackling and static feedback.
I was able to get rid of the problem by purging Pulseaudio.
I was able to temporarily fix the bug by doing a killall on Pulseaudio.

Here's the audio output via lspci -vv:

Let me know if you need anymore information, thank you!

The standard reply to sudden corrupted audio: have you tried the position_fix thing that is described here: https://wiki.ubuntu.com/Audio/PositionReporting ?

Turning off the PulseAudio timing corrected the problem.
It seemed to only happen after opening VLC.
I'll go file a bug report with them as well.

Thank you and my friend thanks you as well! :D
