I have a Samsung Captivate, but those forums have been dead lately so I thought I'd try here in the hopes that it was something in a general setting and not phone-specific. I've read through all the related threads I could find, and tried searching, but haven't seen anyone come up with a resolution. I had flashed ICSSGS Beta 1 a couple weeks ago and then Beta 2 when it was released, and my in-call sound was fine on one call, but on the next attempt it was gone. If I turned on speaker phone then I could hear them, but turning speaker phone off returned to silence. I just tried flashing to DarkyROM 10.2, thinking it was something wrong with the ICSSGS Beta 2 ROM (I had experienced several other issues between those two; prior to that I was using Serendipity 6.4 without any problems), but it persists. Before I try flashing all the way back to stock, I thought I'd try to see if maybe there is some hidden setting that I'm overlooking (all volumes set to maximum; see nothing else specifically related to the way call audio is handled). Thank you for any assistance.
