You stated that it work in the ofw selftest so your hardware appears good.

Run alsamixer from the command like and take a look at what the various 
settings are.  Make sure the mic is unmuted and that the record levels 
are set properly and the v_refout is enabled (unmuted) and DC Mode disabled.

When using alsamixer make sure you switch to the "capture" settings with 
the tab key to see the mic record level.  In "playback" the "mic" 
control is not the microphone record control its the analog mixer 
control which is the level of mic input thats routed back the the 
speaker output.  Muted and zero is the proper setting for that control.

Joyride and microphone

2008-07-19 Thread Robert Myers
I recently upgraded to Joyride and am having trouble with the microphone.

In the powerup selftest the microphone works, but the level of the 
playback is much lower than the powerup chime or the sound sweep test.

The microphone does not work in Record or Measure.

Version particulars:
Firmware q2d16
Joyride 2137
Record 55
Measure 17

Is this a software issue or did my mic die? Things were working before I 
upgraded to Joyride. Anything I can do to check?

If this is a software issue are there libraries or versions I need to 
change?

I'd prefer not to have to go back to 708 just to check this issue out.

Thanks

Bob
