pulseaudio

I am not very experienced in linux and have this problem with microphone which works fine on Windows. Microphone is external one and when listening to recorded sound (both Sound Recorder and Skype Echo Test) you can hear crackling noise.

I fixed output crackling by replacing

load-module module-hal-detect

with

load-module module-hal-detect tsched=0

in /etc/pulse/default.pa but I have no idea how to fix input.

Hardware info:

Card: HDA ATI SB                                    
Chip: Realtek ALC272X

Thanks for help!

I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version. In this case, kernel 3.3 has seen some very good power management enhancements that are… >>> More
