Second attempt to solve sound problems

My sound problems have persisted on my phone. They seem totally random. It occasionally won't give me any voice when I pick up a phonecall or try to call, no ring, I can't hear the other person, and they can't hear me. A soft reboot solves the problem, but then it will randomly come back.

After reading up in the forums, this is a very common problem. And it's definitely conflicting software, each ROM file is most compatible with a specific Radio file. And mine turned out to still be mismatched from when I tried to unlock it. I had the latest official AT&T Windows Mobile 6.1 Kaiser ROM, but not the Radio file that matched best with it. If anyone else is having a similar problem, you can check the chart here to see if your files match up correctly. Since mine did not, I went to the HTC download site and grabbed the full reload file with the current ROM, Radio and installer, and started over Flashing my phone, reloading me contacts, and customizing my phone again. At the HTC site I also picked up the backlight fix file (the backlight turns off after 10 seconds in the original software). So far so good!
