Comment 0 for bug 1583801

The bug is twofold, first when computer boots if the headset (headphones with built-in mic, one audio jack) is plugged in, then there is no sound (via headphones or otherwise). If you plug headphones out and back in, then it usually works as expected.

The second scenario is the same, except that plugging out and back in again doesn't help. In that case, I just restart the laptop, then plug them back in again and it works.

In all cases, microphone works.
