Comment from reader: For me, the instructions above did not still cut it. I had to turn a control "AC97" to 100% (in addition to Mic and Capture to 100%).
I'm I supposed to see the AC97 control? where can I find it?

Yes this is a PC mic (plantronics) and you're right it doesn't have any source of power, it takes it from the PC. However setting V_REFOUT to 3,7 or 2.25 doesn't seem to make a difference.On 16/02/2008, James Shatto <Shadow_7@xxxxxxxxxxxxx> wrote:> Simple mixer control 'V_REFOUT',0

What type of mic are we talking? Electret type mics(the kind that most PC style mics seem to be/use) need a voltage(called a bias voltage, or plug-in power for voice recorders). Without the voltage you need a battery box. Set it to 3.7V, if you can. 2.25 V should also work. 0V and High-Z would be my last choices.
