The issue is that, sometime the microphone is detected and not. I'll try to explain how it is happens. 1) Boot the laptop. 2) Open Skype, and call to "Echo / Sound Test Service" 3) Record a message, and nothing is recorded, i can see how Skype increase the input volume level to 100% trying to detect input. 4) Go to sound settings, select input tabs, see the input volume is on 100%, and the indicator bar is like disable, isn't detecting sound input. 5) Change the volume to 20% and the indication bar start to showing input signal detection. 6) Open Skype, and call "Echo / Sound Test Service". 7) Record a message, and it is recorder, I can heard the message. Is like, the input start working after i change the volumen input setings levels. I'm not sure, if the problem is on PulseAudio or in AlsaDrivers. I attach the pulseaudio logs, (enabled following this instructions: <a class="moz-txt-link-freetext" href="https://wiki.ubuntu.com/PulseAudio/Log">https://wiki.ubuntu.com/PulseAudio/Log</a>) The logs was recorder during the test described above, steps 1 to 7. The test environment is: =============== Laptop brand Positivo BGH; Sist. Op: Ubuntu 14.04 Sound card info: alsa.card_name = "HDA Intel PCH" <meta charset="utf-8"> alsa.driver_name = "snd_hda_intel" device.vendor.name = "Intel Croporation" device.product.id = "0f04" device.product.name = "ValleyView High Definition Audio Controll" Somebody can tell me, based on logs if the problem is on PulseAudio or on AlsaDriver ? Do you need another information or logs ? Thanks in advance. Gustavo Duarte. </body> </html>
