Somewhere after the LGNPST I ran into problems with the sound volume settings being completely ignored and this issue appears across multiple roms. I'll have the settings set to silent and it'll still play some odd sound whenever I receive an sms. When I try to change the sounds, nothing plays when I am previewing the sounds and if I select one the settings will crash. The ringtone files do exist in /media/audio/ringtones and they play correctly in Apollo. I have also downloaded Zedge and used it for setting the sounds inside the settings screen and it does not play the sound when previewing and crashes when I select a sound. Setting the ringtone inside of the actual Zedge application does work for the notification ringtone, but does not work with phone ringtone (it does appear to be changed in settings, but no sound is played during calls). Furthermore, when I attempt to set the sound in Hangouts for either SMS or regular hangout messages, it does not change from "Silent" but does not show any crash messages or anything.
In a possibly related note, every time I flash a new rom it will get stuck on activation until I just skip it. However, data services work completely fine. I have no problems with making calls, 3G/LTE, sending and receiving sms including pictures.
Any help would be greatly appreciated. Thanks.
