[One (M8) Original Android Development] bigeasy911:
I have an issue. I have flashed CM 11 you can see all detailed specs below in the phones sig It was running stock ROM rooted S-off at the time. Before flashing the CM rom I had done full firmware update to the latest via XDA thread see sig for version info.

The very first issue I had started the first time after boot that I opened the dialer app. There was a loud beep followed by equally loud static. This was unaffected by muting or changing volume and would persist for roughly 5 seconds. I would happen anytime a app or setting was opened or closed or any major change.

This I tracked down to some sort of audio driver issues in whatever the CM 11 audio apk (or possibly the amp apk driver?) uses or something to that effect. I fixed this issue by installing viperaudio.apk which offers a few different audio drivers. I picked the super high quality one and upon reboot all static issues were gone and have not come back with days of use and reboots.

I have to say I am surprised a bug like that has gone for so long on stable release. But I tend to wonder it maybe it was caused by the newer firmware update as this came after from I can see the last build update for the CM11.

Regardless it seems to have been an easy fix so moving on.....

FYI: System is encrypted and has worked without issue and also seems to be compatible with this version of TWRP recovery. I can go into bootloader and upon choosing recovery I get the password screen. Once entered correctly TWRP loads without issue.

**The current issue I have:

Call settings via phone dialer setting button on bottom right. I have what seems to be duplicate menu listings. Under "Other Call Settings" everything looks "ok" until you get to "voice mail privacy" check box line. I assume that subsection should stop there and move onto "Internet Call Settings";. Instead, the last three menu choices repeat.

Those being:

Call Forwarding

Call Waiting

Voice privacy (Enable enhanced privacy mode)

I end up these three listed twice in that order and then repeated. This in itself would not be a big deal to me but it seems at least so far that Call Forwarding and Call Waiting does not work (no sure a way to check if the enhanced privacy is working but was checked by default and I have not messed with it)..

I have also tried both of the duplicate choices for call forward /waiting and its the same.

In the submenu to call forward I have:

Always Forward

Forward when busy

Forward when unanswered

Forward when unreachable

Deactivate all

The issue is when I choose any of the choices I get a activate and deactive buttons.

For Forwarding: I choose activate and then enter a phone number in the popup menu and click the enable button. The result is it ends up dialing that number right there like a normal phone call from the dialer. I then go back in and check the settings and its still clear so none of my entries took.

Call Waiting when I click activate I got a popup error of some system apk ,I think, but I did not catch it before it disappeared. Now even with full reboots the activate button does nothing at all.i.e no error or stop of an apk as it did that very first time. Just nothing.

??????

I really need these to work. I could care less about the duplicate choices I just need them to work. While I could find plenty of people wit the audio static and distortion issues I could not find anything with these call settings issues. I am usually good at finding posts and threads on these kinds of things but on this one nothing so far. Any help or guidance would be greatly appreciated.
