It works well with my sound recording app and other similar apps, but when i try to use it for a normal phone call I have to yell into the mic if the other person is to hear.
Is there a possibility it has something to do with the rom?
Dunno. I don't have anything like it to test with. It could be the other persons' phone. It could be an FXP issue. I assume you've turned the in-call volume (while in a call) up to max while the headset plugged in?
(1) Try the microphone test in the MIUI Service Menu (dial *#*#MIUI#*#*)
(2) Install FXP-CM7 and see if it does the same.
Even if it is an issue with MIUI, I wouldn't know where to start to fix it because I have no such accessory. Sorry.
EDIT: After further research I found that it might be a kernel issue (with values somewhere in /sys/devices/ which come from the kernel) so can you tell me which kernel you are using? If you are using CosmicUI kCernel, please test with FXP-CM7 kernel.
EDIT2: I also just read that if you Mute then Unmute a call it fixes a low-microphone bug in MIUI. Try that. Annoying I know, but it will at least narrow it down.
