After discussion with Kailang, he concludes that it's likely to be a hardware issue - nothing serious can be done in the software level.
If we introduce the workaround,
- No more static noise in headset
- The headset volume will be drastically decreased, but you can increase the maximum volume in PA to 150%.
- The traditional microphone can still be used, but without level 2 and 3 amp.
So it's up to you guys - if you guys think it's a fair trade off, I'll upstream the fixup. If not, there's nothing more we can do in software level.
