Did you get the Siyah CM10 Test Kernel or the normal ICS 3.5.1 version? I would bet the 3.5.1 ICS version. My apologies...I should have been more specific.
As far as I can tell, the Siyah kernel generated by Ktoonsez for the SGH-I777, has separate ICS and JB versions. The GT-I9100 Siyah kernel is version 3.5.2 and seems to be for BOTH ICS and JB roms but that is only for that phone.
At this time, Ktoonsez' Siyah has mic swap and no mic swap versions for ICS 3.5.1 but the CM10 test kernel seems to be without mic swap, which would cause your call audio to be low since the top mic is being used instead of the bottom mic. Without mic swap is only for AT&T leaked roms (and we all know AT&T won't be releasing JB to us anytime soon). Please go thank or donate to Ktoonsez anyway because you know he will be on top of this in the future. http://forum.xda-developers.com/show....php?t=1592228
I would highly recommend the Dream kernel WITH mic swap. This should fix your problem. Don't forget to Thank or Donate to Team Skyfire if you use their kernel. http://forum.xda-developers.com/show....php?t=1788148
I am using the 2.6.9 version of the Dream kernel (with mic swap) with great results. For some reason, which is explained in their thread, 2.6.9 is actually newer than their 3.2.9 version. Something to do with the TWRP recovery for one and not the other.
Please let us all know your results using the proper kernel.
