@David I solved the problem by installing HDAAnalizer.py following instructions in www.alsa-project.com and follow David Henningsson instructions in the thread I mentioned earlier:
go to node 0x14, and make sure connection 0x17 is selected After selecting connection 0x17, the internal mic started to work. Also, I have added options snd-hda-intel model=laptop in alsa-base.conf. I hope this info helps you find a definite solution to the problem. Let me know if I can be of help. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/688423 Title: [Conexant CX20583 (Pebble HSF)] Recording problem -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
