After rom install-help!!!!..volume is gone!!!

[da1stprince]

i always try out the latest rom to test out and enjoy, so i (properly)installed the latest rom from kirvin 3.5 stock rom and after the install i lost all volume... i enabled all sounds, screen taps,turned the volume on high and still no volume at all. is it possible that a hardware driver was kicked out of the phone during the process of the install? i tried reverting back to past roms,but there was no change at all. i had this same problem happen to a friend of mine who never changed her rom(she mostly uses her 6700 as phone and not much else). she took it to sprint for them to fix the volume and they gave her a new treo to replace it. i don't want to give up my 6700,so can anyone please give some sound advice on what to do about this problem? any and all info concerning this issue will be greatly appreciated...
