[Q] Bad sound quality in phone calls

[Random76]

Hi.
I saw several threads on the matter but with no solution and they're from September 2010... maybe some new info has emerged...

I just bought the Captivate (not using with AT&T). It was with android 2.1 and with a decent outgoing sound quality.
I upgraded to 2.2 (installed [ROM] Obsidian V4.2) and now the outgoing phone calls are with bad quality.
The incoming sound is perfect. People tell me I sound bad as if from a very distant and deep submarine... I tried re-surfacing but alas it didn't help...

Is there any solution? driver? another ROM proved with quality? since at first it worked fine I imagine it's a software not hardware problem.
Thanks in advance.

I found that most of the newer 2.2 roms are based on the I9000UGJK3 modem and kernel which allows us to have HSUPA, but call quality suffers greatly. Until theres a source released for us cappy users, we're stuck with this issue. I went back to cog 2.16 because of that

Actually that new modern you mentioned is part of my daily driver. You just have to make sure you paiute the current modem with the correct rom.failure to do so will result in the results you have received.

I am also having horrendous call quality issues with that I9000UGJK3 setup.

So basically no one knows what can be done and I'm stuck with an amazing phone that can't be used as a phone....
Not able to use warranty - bought in the states and not living there....

Obsidian hasnt been updated in some time. Try http://forum.xda-developers.com/showthread.php?t=863776, this rom is my fav so far, call quality much better, not great but better, FAST and has all the eye candy plus more. remember to flash to stock first, JF6 then master clear, use this http://forum.xda-developers.com/showthread.php?t=731989
