Tanu, you have just hit the nail on the head. Awesome !!! After sound mic is broken, running "paplay /usr/share/sounds/freedesktop/stereo/bell.oga" fix it. As you told, skype changes the sample rate. On other hand, if I running "paplay /usr/share/sounds/freedesktop/stereo/bell.oga" before skype, it avoid the input sound break. To be more clear I did following two tests. A) To check your guest. 1) boot 2) open Skype, and clall "Echo sound / service", NO msg was recorder. 3) run "paplay /usr/share/sounds/freedesktop/stereo/bell.oga" 4) open Skype, and clall "Echo sound / service", msg was recorder, mic start to WORKING. B) In order to find a workaround to fix it. 1) boot 2) run "paplay /usr/share/sounds/freedesktop/stereo/bell.oga" 3) open Skype, and clall "Echo sound / service", msg was recorder, mic WORKS. I wonder if there is another way more elegant, to fix it ? (Avoid Skype or other apps change the sample rate and break the sound). Thanks in advance.
