I asked Jerry about this earlier in this thread. IIRC, he said it is a problem with the cyanogenmod port and he does not like to mess with the actual phone script.
In other words, a fix is not in the works.
I've learned to just do the volume trick. Doesn't bug me anymore.
Just to clarify this issue. It is a known issue on Gerrit, the code review system for CyanogenMod. It is unknown when it will be resolved.

BTW, your ROM was the first ROM I flashed "I loved it then and I love it now". I am so glad to see you are always working and making your ROM even better. I have noticed a lot of the other ROM makers seem to just stop working on their ROMs, I am so glad you are sticking with it "Good Job". I will be switching back to your ROM later today and look forward to seeing what you come up with next.
Not a huge deal, though. I'm never more than twenty feet from an electrical source. What can I say? I'm old school nerd!
