wireless headset USB microphone volume control

Jasmin

I have just started to explore the functions of the wireless headset development kit and flashed the "wireless usb headset" default project with the wireless configurator.

Everything works as expected except the volume gain control of the microphone for the USB soundcard (windows 7). I cannot move the volume/gain slider in the microphone properties dialog of usb-soundcard's record settings. I have tried to change the minimum volume for the master and for the slave. When I increase the fixed offset on the slave, the microphone gain is higher, but I am still not able to change the microphone volume of the usb-soundcard.

Some ideas to resolve that? :-)

    Hi Jasmin,

    In Windows XP I'm able to slide the microphone gain slider bar. It's important to set the "Minimum volume" to something negative (e.g. -30 dB) in the Master's Input volume control. In the slave's Input volume control you should then select "Remote" with Fixed offset = 30 dB and Minimum volume = -30 dB. I haven't tried this in Windows 7, but if this doesn't work please let me know and I can try to have a look at it.

    Hi Kristoffer,

    thanks for your message!

    I configured the devices exactly as you mentioned and flashed again, removed and plugged in usb -  but unfortunately the problem persists. The mic gain slider in the properties dialog of the headset record device does not move.

    I use Windows 7 Professional 64bit. It would be really great, if you could have a look at it!

    Hi Kristoffer,

    you were right - but the win7-system needed an additional restart after the flashing process (despite it's now 10 years after win9x :-(  ) - now it works with the settings you proposed.

    Thank you very much!
