Hi all, I'm using a pair of Sennheiser CX 275 S earbuds. They have a built-in microphone that sounds great when using my phone and tablets, but on my Fedora 21 laptop suffers from so much static that I basically can't use them for calls. Therefore I'm trying to understand whether I can convince PulseAudio to better filter out the static. Could somebody please describe my options? I've found scattered mentioning of the module-echo-cancel module on the web but can't seem to add it to my config without triggering the "between a sink and its monitor" error. I'm not even sure whether an echo cancellation module is the right choice for noise reduction, but some sources suggested it. So, please advise... Thanks, -C.
