Wednesday night, sometime around 8-8:30 PM Central, near the A106 area, I lost vox only. That is something new, as I always lose all sounds. I was in a GV, and had driven quite aways, and as such I did not want to risk the usual CTD I get when using ".resetv". I waited for about 15-20 minutes, and finally decided to try ".resetv 1" (no, I'm not using the quotes when I do it). I tried repeatedly for the next half hour or so, but it never restored vox, despite showing the dialog in the text buffer. Eventually, about 20 minutes or so later, after I had moved to another area, I got booted. Never lost sounds or vox the rest of the night.
I hope HTC has not lost this thread, and we are not wasting time posting information that will not be of any use. It would be nice, if it is not too much trouble, to have someone from HTC reply, and tell us that they either have enough information, they can't use the information, or they'd like us to keep posting the information because they are using it.
