I found out a workaround for my case! It consists of muting everything in alsamixer except Master, PCM and Externel Amplifier. The strange thing is that the microfone works even when it is muted. And it never stopped working, because when I first discovered this bug I recorded my voice with arecord. I couldn' t hear it back them, but now I listened that file and my voice is there.
I could try to randomly start unmuting the channels to check what is the first one which reveals the bug, but I've lost my weekend already and now I have no time left :-( -- [Feisty] Very low volume on Toshiba satellite a100-155 https://bugs.launchpad.net/bugs/93859 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
