<span class="quote">> are there any specification about dB range for LifeChat LX-3000 ?</span >
I haven't configured (nor know how to) any dB ranges for the LX-3000 headset.
I don't know if Microsoft has published any technical data about this headset.

I don't have any speakers connected to the onboard soundcard. I'm using a USB
headset as it's easier to plug into the USB hub on top off my desk, rather than
plug into the audio jacks on the PC under my desk. A USB headset is also more
convenient as there's only one connector, rather than speaker and mic jacks on
analogue headsets.
This doesn't help fix the bug, but gives context why someone may use USB audio
hardware exclusively.

s/headwaters/hardware/ ?
Is there a way this can be made the default for LX-3000 users? Is the problem
that the LX-3000 is incorrectly reporting its supported dB range? If the bug
is in the LX-3000 hardware, does pulseaudio have a whitelist/blacklist of
good/bad hardware that would allow it to use appropriate settings without
individual users having to reconfigure? Even better would be a more generic
solution that's not restricted to LX-3000 devices - if that's possible.</pre>
